Doric 450
The 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
benchtop units.
A custom-designed dual integrated circuit set
gives you a single instrument with wider
temperature ranges, higher resolutions, and
longer performance than other handheld
thermometers. Data hold freezes the displayed
reading for safe viewing away from hazardous
measurement locations.
Battery life is unsurpassed, with a single 9 V
battery providing more than 2000 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. The 450s are available in
thermocouple, RTD, or thermistor
configurations. Please specify when ordering.
