Keysight's U1200 Series is a portfolio of handheld digital multimeters built as part of the company's Handheld DMM Test Tools line for electrical and electronics testing in real-world field conditions. Across the series, these True RMS handhelds are engineered around practical, jobsite-ready functions: high-contrast OLED displays on selected models, continuity checks with audible and flashing alerts, and built-in flashlights that illuminate the test area while you measure. The line is designed to keep a technician equipped whether the work happens in dark, noisy, or hazardous surroundings.

The U1200 Series handhelds are intended for installation and maintenance of machinery and electrical systems, where numerous quick checks and fixes are often required under hazardous conditions. Stated tasks across the series include inspecting power supplies for harmonics, detecting glitches in switch systems, monitoring differential temperature, isolating faults, and general electronics troubleshooting. For technicians and industrial test engineers, the rugged models are positioned to help keep a production line running and prevent unplanned shutdowns.

ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments you order are managed under one roof from receipt to shipment. That combination lets engineers and technicians source U1200 Series handheld meters with confidence in both condition and availability.

Brand Heritage

These handheld tools carry the Keysight Technologies brand, the continuation of a test-and-measurement lineage that began at Hewlett-Packard. Hewlett-Packard's test-and-measurement business was spun off as Agilent Technologies in 1999, and that business became Keysight Technologies in 2014.

Compare Other Models in This Series

The Keysight U1200 Series gathers Keysight's handheld digital multimeters into a single family of True RMS instruments that share a rugged, field-oriented design and a common wireless Remote Link option. The series is organized into tiers that differ primarily in display resolution-from 6,000-count models through 10,000-, 30,000-, 50,000-, and 60,000-count models-alongside differences in accuracy, battery life, environmental sealing, and specialized measurement functions.

Rather than a single configuration, the family lets a buyer match resolution, ruggedness, and feature set to the work at hand while keeping a consistent operating experience and the same optional IR-to-Bluetooth connectivity across models. The comparison table below summarizes how the individual models line up.

Each new model linked below is its own dedicated product page with condition-matched pricing, so you can select the exact U1200 Series handheld that fits your application and budget. Choose the model that matches your required resolution and functions, then review its new listing for current availability.

The clearest dividing line across the family is display resolution and DC accuracy. The 6,000-count models provide essential True RMS measurement, the 10,000-count U1240C Series adds a dual display, up to 0.09% basic DCV accuracy, up to 400 hours of battery life, IP 67 sealing, and 3-meter drop protection, and the 30,000-count U1270 Series measures up to 1000 V AC/DC and 10 A (20 A for 30 s) with a -40 to 55 degrees C operating range and IP 54 protection.

At the higher-resolution end, the 50,000-count U1250 Series adds a built-in square-wave generator and frequency counter with up to 0.025% accuracy, while the 60,000-count U1280 Series pairs that 0.025% basic DCV accuracy with a dual display and battery life up to 800 hours. Specialized functions-Vsense non-contact detection, harmonic ratio, ZLOW, Smart Omega, and low-impedance mode-appear on specific models as shown in the comparison table; capabilities are not cumulative across tiers, so confirm each model's own row before ordering.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Keysight Remote Link wireless Bluetooth connectivity requires the optional U1117A IR-to-Bluetooth adapter.

Important: Adjustable test output voltage from 10 V to 1.1 kV (1 V step) on the insulation resistance testers is available only on selected models (U1453A/U1461A per the datasheet footnotes).

Important: Within the U1230 Series, Vsense non-contact AC voltage detection is available only on the U1233A.

Important: The U1610A/U1620A handheld oscilloscope provides floating measurement with two channel-to-channel isolated CAT III 600 V channels.

Recommended pairing: combine the optional U1117A IR-to-Bluetooth adapter with the U1115A remote logging display to view and log readings wirelessly at an extended range of up to 100 meters.
