The Stanford Research Systems SR630 is a 16-channel thermocouple monitor designed to read, scan, print and log temperatures or voltages. Using any one of seven standard thermocouple types, it reads temperatures from −200 °C to +1700 °C and displays results in °C, °F, K, mV or V on the front panel. Each of the 16 channels can be set independently to monitor either temperature or voltage, giving the instrument broad configuration flexibility for multi-point monitoring tasks.
The SR630 is built for remote monitoring applications, where it can time-stamp and store up to 2,000 readings in non-volatile memory for later analysis. Its isolated differential inputs and 250 V breakdown level let it tackle difficult applications such as temperature profiling of electrically live equipment. The four analog outputs can drive chart recorders or provide a feedback signal for proportional temperature control systems, and the integrated 1:15 analog multiplexer makes the unit useful in ATE systems and many other monitoring applications.
ValueTronics supplies the SR630 from our own 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold our inventory rather than sourcing to order. Every pre-owned unit is supported by that in-house operation: pre-owned units are inspected and functionally verified by our technicians before they ship, while new units ship factory-sealed exactly as received from the manufacturer.

Important: Maximum common-mode input: ±200 VDC. Input protection: 250 Vrms.
Important: Accuracy errors are for the SR630 only. Standard errors for thermocouple wire are 2 to 5 times the error due to the SR630.
Important: Thermocouples are not included with the SR630; K-type thermocouple probes are listed separately in the ordering information (O630KF1, O630KF2, O630KT1, O630KT2) and must be ordered to use the instrument.
Recommended pairing: the SRS O630-series K-type thermocouples (O630KF1/KF2 fiberglass or O630KT1/KT2 teflon, 5 ft and 10 ft) and the O630RMS/O630RMD rack-mount kits listed in the ordering information.
This pre-owned unit is inspected and functionally verified in-house before it ships and is backed by our pre-owned warranty. To confirm its exact condition, firmware revision, installed options, or included accessories for your application before ordering, contact our Test Architects.
ValueTronics supplies both new and used test and measurement equipment. New units ship factory-sealed, exactly as received from the manufacturer; every used unit is inspected and functionally verified in-house at our 20,000 sq ft secure facility in Elgin, Illinois before it ships. Our Test Architects can help you select the condition, calibration, and configuration that fit your application.
Please review the Manufacturer's Data Sheet to verify published specifications. Feedback on this webpage is always welcome — please reach out to your Test Architect at any time for questions or concerns. Thank you, we truly appreciate you being our customer.
