It combines low-noise voltage measurements with resistance and temperature functions in a single benchtop instrument, providing 7½ digit resolution with 100 pV voltage sensitivity and 100 nΩ resistance sensitivity. The instrument is RoHS compliant and applies to serial numbers MY61000101 and SG61000101 onwards.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe 34420A is designed to take the uncertainty out of low-level measurements. Low-noise input amplifiers and a highly tuned input protection scheme bring reading noise down to 8 nVpp on the 1 mV range over a 2-minute observation period. Combined with 7½ digits of resolution, selectable analog and digital filtering, 2 ppm basic 24-hour DC voltage accuracy, and a shielded copper pin connector, the instrument supports accurate, repeatable measurements for nanoVolt-class work.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics International stocks and supports the Keysight 34420A from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every nanoVolt-class instrument we list is inspected and performance-verified by our technicians before shipment, so the condition grade and specifications you see in the listing reflect what the instrument actually delivered on our bench — not a seller's description. We've supported customers across calibration labs, semiconductor characterization groups, and standards laboratories since 1992, and we back every unit with our standard performance warranty.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe 34420A traces to Hewlett-Packard's test and measurement heritage.

The Keysight Agilent HP 3852A is set up to handle many different transducer inputs including thermocouples, thermistors, RTDs, and strain gages, as well as being ready to measure DC volts, currents, resistances, pulse counts, frequencies, and more. The Keysight Agilent HP 3852A mainframe has eight (8) slots for plug-in function modules, and has provisions for extending the mainframe (the Keysight Agilent HP 3853A) for large systems requiring more plug-in cards. Choose from three digital voltmeters to meet your measurement needs. The voltmeters can be used in the mainframe or the extenders, and multiple voltmeters are allowed in each mainframe. With the Keysight Agilent HP 3852A you can choose from a complete set of input and output plug-in modules that provide a variety of measurement and output-controlling capabilities. The Keysight Agilent HP 3852A has built-in, 68000-based intelligence to increase the speed and effectiveness of the system and to collect, analyze, and respond to data. Control decisions are handled quickly using subroutines running within the mainframe (not having to communicate via GPIB to an external computer in every case). This intelligence can be used to return only the most significant data to the computer, increasing its efficiency with other tasks. The power of this front-end intelligence, in combination with an 9000 Series 300 computer and optional data acquisition software, adapts easily to testing your product or characterizing your processes. Or, if you prefer, you may configure your system to run with a PC as the host computer, possibly incorporating the Graphical Programming Language from Agilent VEE.\u003c\/p\u003e","brand":"Agilent","offers":[{"title":"Default Title","offer_id":49232032989431,"sku":"agilen_3852a","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/0443\/2631\/files\/agilen_3852a.jpg?v=1735290250"},{"product_id":"44425a-agilent-data-logger-used","title":"44425A Agilent Data Logger Used","description":"\u003cp\u003e\u003cstrong\u003eAdditional Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e16 Channel Isolated Digital Input\/Interrupt Assembly\u003c\/li\u003e\n\u003cli\u003eSense up to 16 channels of digital data\u003c\/li\u003e\n\u003cli\u003eThe first 8 channels can also be used as interrupt lines to detect transient signals\u003c\/li\u003e\n\u003cli\u003eInputs of 5, 12, or 24 volts are acceptable\u003c\/li\u003e\n\u003cli\u003eA five volt supply is provided for driving external contact closures and open collector outputs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe HP 44425A (option 050) assembly can sense up to 16 channels of digital data.

Typical applications listed include medium- to high-density switching and measurement, electronic functional test, design verification, data acquisition, monitoring multiple signals over time, routing individual signals between instruments, and controlling external devices such as microwave switches, attenuators, solenoids, and power relays. A data acquisition system, in general terms, is an instrument that converts physical or electrical signals from a device under test into digital values that can be logged, analyzed, and acted upon over time — and the 34980A combines that role with the signal-routing flexibility of a switch matrix in one chassis.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics stocks, inspects, and ships the 34980A and its plug-in modules from a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used 34980A mainframe and module that leaves the building is performance-verified by our technicians against the published Keysight specifications, and we maintain depth across the multiplexer, matrix, general-purpose, RF, and system-control module families so that a customer expanding a configuration can typically source new and used modules on a single purchase order — something most direct-channel sources cannot provide.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe 34980A originated under Agilent Technologies, the test and measurement company that was spun out of Hewlett-Packard in 1999.

Rather than route every channel through external signal conditioning, the internal autoranging DMM measures 11 different functions directly — temperature via thermocouples, RTDs and thermistors; DC and AC volts; 2- and 4-wire resistance; frequency and period; and DC and AC current. Per-channel configurability lets each channel be set up independently, so a single mainframe can mix temperature, voltage and resistance scans across one wiring harness.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFunctionality is defined by the plug-in modules installed in the three slots. The family covers low-frequency armature and reed multiplexers, a 40-channel single-ended multiplexer, a 4x8 two-wire matrix switch, a 20-channel actuator\/general-purpose switch, dual-channel 50-ohm and 75-ohm RF multiplexers, and a multifunction module that adds digital I\/O, analog output and totalizer capability. Each module carries its own microprocessor and screw-terminal connectors, and the internal analog bus routes low-frequency multiplexer signals directly to the internal DMM without external cabling. Channels and functions can be added later by changing modules as an application grows.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eValueTronics International has supplied test and measurement equipment from its facility in Elgin, Illinois since 1992.

The only functional difference is the host-PC connectivity, so the choice between them is an interface decision rather than a measurement one.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eChoose the 34970A when the test system standardizes on GPIB or RS-232.

If you need to “zero” a large number of thermocouples to a known reference temperature before starting a temperature profiling or validation test, the 2638A will normalize all readings to your reference channel at the push of a button and store the offsets for reference in a supporting data file. If you are conducting chamber tests, heat treating tests under AMS guidelines, or validating temperature devices under 21 CFR regulations, Hydra Series III makes it that much easier to comply.\u003c\/p\u003e","brand":"Fluke","offers":[{"title":"None","offer_id":49232047538423,"sku":"fluke_2638a","price":0.0,"currency_code":"USD","in_stock":false},{"title":"NIST Traceable","offer_id":49232047571191,"sku":"nist_traceable","price":315.0,"currency_code":"USD","in_stock":false},{"title":"NIST Traceable with Full Data","offer_id":49232047603959,"sku":"nist_traceable_data","price":490.0,"currency_code":"USD","in_stock":false},{"title":"ISO IEC 17025 Accredited","offer_id":49232047636727,"sku":"17025","price":630.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/0443\/2631\/files\/fluke_2638a_1.jpg?v=1735290579"},{"product_id":"42270-extech-data-logger-used","title":"42270 Extech Data Logger Used","description":"\u003cp\u003e\u003cstrong\u003eAddtional Features:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eRecords Relative Humidity and Temperature in storage containers, shipping vans, freezers and more\u003c\/li\u003e \u003cli\u003eLogs data for days, weeks or months up to 1 year battery life\u003c\/li\u003e \u003cli\u003eMultiple Dataloggers can be programmed and data downloaded from one single docking station.\u003c\/li\u003e \u003cli\u003eProgrammable sampling rate from 1 second to 2 hours\u003c\/li\u003e \u003cli\u003eProgram the logger, analyze and store data using Windows 95\/98\/2000\/NT\/ME\/XP compatible software\u003c\/li\u003e \u003cli\u003eView both humidity and temperature on LCD display\u003c\/li\u003e \u003c\/ul\u003e","brand":"Extech","offers":[{"title":"Default Title","offer_id":49232038232311,"sku":"extech_42270","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/0443\/2631\/files\/extech_42270.jpg?v=1735290583"},{"product_id":"44701a-agilent-data-logger-used","title":"44701A Agilent Data Logger Used","description":"\u003cp\u003e\u003cstrong\u003eAdditional Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDC volts ranges: 30 mV, 300 mV, 3 V, 30 V, 300 V \u003c\/li\u003e\n\u003cli\u003eDC volts accuracy: 0.008% \u003c\/li\u003e\n\u003cli\u003eResistance ranges: 30 Ω, 300 Ω, 3 kΩ, 30 kΩ, 300 kΩ, 3 MΩ \u003c\/li\u003e\n\u003cli\u003eResistance accuracy: 0.015% AC volts ranges: 200 mV, 2 V, 20 V, 200 V \u003c\/li\u003e\n\u003cli\u003eAC volts accuracy: 0.5% \u003c\/li\u003e\n\u003cli\u003eMaximum input voltage: 350 Vpeak or 250 Vdc between any two points (terminals or chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe Agilent HP 44701A is a Integrating Voltmeter that directly measures DC voltage, AC voltage and resistance and lets you accurately measure small signal changes in noise environments.

The Hydra Data Bucket is used for standalone monitoring operations where data is collected on the memory card and later retrieved at a PC, and for PC-based data acquisition where the RS-232 link feeds readings directly into application software. The datasheet describes its role in test and monitoring systems, remote-location data gathering, and applications that mix standalone recording with periodic upload via the Hydra RS-232 port, an optional external PC memory card drive, or a standard PCMCIA slot on the user's computer.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eBrand Heritage\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eFluke Corporation is the original manufacturer of the Hydra Series. The Hydra family was developed during the era when Fluke operated as a standalone public company before its 1998 acquisition by Danaher Corporation. Fluke has continued to operate under its own brand name through the Danaher era and into the current Fortive Corporation, which was spun off from Danaher in 2016 and now serves as Fluke's parent company.\u003c\/p\u003e\u003ch2 style=\"display:block; clear:both; text-align:left; font-size:22px; margin:24px 0 12px 0;\"\u003eCompare Other Models in This Series\u003c\/h2\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe Hydra Series comprises four data acquisition instruments built on a common 21-channel Universal Input Module front end with shared measurement specifications. All four models share the same analog measurement performance, the same isolation and safety ratings, and the same Universal Input Module that accepts thermocouples, RTDs, DC and AC voltage, resistance, and frequency without external signal conditioning.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe models differ along two axes: nonvolatile data storage and host interface. The 2635A Hydra Data Bucket adds PCMCIA memory card storage to the RS-232 interface, supporting standalone logging with later upload. The 2625A Hydra Data Logger provides internal nonvolatile memory storing more than 2,000 scans with RS-232 transfer. The 2620A Hydra Data Acquisition Unit has no internal nonvolatile storage and is designed for direct PC connection via RS-232, while the 2620A\/05 substitutes an IEEE-488 interface for the RS-232 (the two interfaces are mutually exclusive when IEEE-488 is in use).\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eEach pre-owned Hydra Series model below is its own dedicated product page with condition-matched pricing, inventory status, and quote workflow.

Its PCMCIA memory card storage, multiple card capacity options (256 KB through 4 MB), and ability to transfer real-time data to a PC while simultaneously recording to the card distinguish it from the internally-stored 2625A and the PC-tethered 2620A. The datasheet explicitly identifies the 2635A as the right choice for gathering and transporting large volumes of data and for working extended periods from remote locations.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eThe compare-models table below summarizes the four Hydra Series variants by storage type and host interface. All four share identical analog measurement performance — the Universal Input Module, the 17-bit ADC, the channel count, the isolation ratings, and the temperature, humidity, and EMI specifications are common across the family.\u003c\/p\u003e\u003cp style=\"margin:0 0 12px 0;\"\u003eSelection across the family is driven by deployment mode rather than measurement performance. Standalone field logging with later card retrieval favors the 2635A. Standalone logging with serial upload at a fixed location favors the 2625A.

Chroma loggers are with 1000 VDC channel to channel isolation, which means they can attach thermal couples to objects with high electricity, such as batteries, solar cells, working PCB, etc., and still get correct data. Many competitors are just malfunctioned or even damaged in those cases. Data retrieve in Chroma loggers are in a parallel architecture, while most of competitors use a sequential multiplexing method.
