Thermistor Calibration Prover Box °F

Cooper-Atkins Model 9320-NIST

Test and validate the calibration accuracy of your Thermistor Instrument with the °F Thermistor Prover Box. The 9320 Thermistor Prover generates a low voltage to simulate four preset USDA Compliant temperatures. Temperature settings for the 9320 are -10 °, 32 °, 72 °. When the Thermistor Instrument is plugged into the Prover box with the Dual Jack Prover cord 9314 (included with your 9320, it should read the designated temperature selected with the dial. Please allow extra time for delivery of the NIST certified option.

Please note - The 9320-NIST will verify the calibration of your Cooper-Atkins thermistor based thermometer but it will not verify the accuracy of the probes used with your thermometer.

Great product. Awesome company . Thank you

Used it after receiving it and it appears to work OK.

I am sure your product is fine. It is an outdoor thermometer sensor. It didn't work. I believe the indoor clock receiver doesn't work. Thanks for asking.
