Doric 450-TH Thermistor Thermometer


Doric 450TH Thermistor ThermometerThe Doric 450 Series digital thermometers are among the most accurate, reliable, and convenient handheld instruments ever developed. Using a unique, patented noise reduction circuit, the Series 450 achieves the high repeatability and accuracy of line-powered bench top units.

A custom-designed dual integrated circuit set gives you a single instrument with wider temperature ranges, higher resolutions, and longer performance than most other handheld thermometers. Data hold freezes the displayed reading for easy viewing away from difficult measurement locations.

Battery life is unsurpassed, with a single 9V battery providing more than 1200 hours of use. An externally available zero pot, conveniently located at the back of the instrument, lets you match ice point calibrations to specific probes for even greater system accuracy.


Price:  $ 335


The 450 is also available in thermocouple, RTD, and thermistor configurations. Please specify when ordering.
