9320 & 9321 Thermistor Prover Boxes

Test and validate the calibration accuracy of your Thermistor Instrument with the °F / °C Thermistor Prover Boxes. The
9320 and 9321 Thermistor Provers generate a low voltage to simulate four preset (USDA Compliant) temperatures.
Temperature settings for the 9320 are -10°, 32°, 72° and 140°, and for the 9321, -25°, 0°, 20° and 60°. When
the Thermistor Instrument is plugged into the Prover box with the Dual Jack Prover cord 9314, it should read the
designated temperature selected with the dial.
