GENERAL DESCRIPTION
The Minitherm HI 8751, HI 8752 and HI 8753 are accurate,
general purpose, thermistor thermometers designed for simplicity of
use. The large LCD provides clear, easy-to-read digits that can be
read at any angle. A rotary knob on the front panel switches the
instrument from the OFF position to the desired measurement range.
HI 8751 measures temperature in Centigrade whereas HI 8752
reads temperature in Fahrenheit and HI 8753 has both ranges
available for measurement.
Each meter comes supplied with the precalibrated and interchangeable HI 765BL temperature probe, a 9V battery and an instruction
manual.
