For $250 you get a high precision thermometry system with accuracy to ±0.05°C from 0 to 70°C (±0.1°C to 100°C). You would pay $1,500 for a conventional meter and probe with this accuracy that logs data and includes a traceable certificate.

The USB Reference Probe is ideal for calibration labs and instrument shops performing routine calibrations in baths and dry block calibrators. Its 1/8" (3.2mm) probe diameter means fast response and increased flexibility in performing comparison calibrations. Simply insert the probe into a stirred laboratory bath or dry block along with your test thermometers and compare readings over multiple temperatures.

If you're still using mercury thermometers, now is the best time to replace them with an easy-to-use digital thermometer with super high precision. Plug the USB probe into your PC, open the software and you've got a digital reference thermometer without having to squint or interpolate to get your readings. Connect up to 10 probes within the same software window and monitor multiple applications simultaneously (depending on the availability of USB ports).

Each probe includes an individual NIST-Traceable calibration certificate with test data at 0, 25, 70, and 100°C. The free software gives you the ability to store data to the PC and setup hi and low alarm conditions with email alerts.

*Rating is for SST sheath only. Transition, strain relief, cable and USB connector are rated to 60°C (140°F).
