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.

La Crosse Technologies V10-TH

The La Crosse V10-TH Wireless Weather Station (Model No. C84343) is absolutely wonderful. The setup was easy with the Quick Setup Guide provided with the unit. The packaging contains additional support information with the website and phone number if there are questions. I especially liked the daily high low readings and the color on the unit! Tech Instrumentation provided great communication as to the availability of the product and shipping details. If fact, it arrived one day prior to the estimated delivery date. I would absolutely recommend this product and Tech Instrumentation for anyone looking for an indoor/outdoor weather station!


I needed a replacement as my original sensor no longer worked. This one works fine.

Excellent Customer Service!

I can't way enough about the customer service at Tech Instrumentation. I was looking for a hard to find specialty part, which the manufacturer told me would need to be custom made. After calling and speaking with a representative at Tech Instrumentation, the part was located and order was filled, right over the phone. Delivery was prompt, and instrument is working great. Highly recommended company for lab supplies!

Worked great

Put batteries in and worked great
