GENERAL DESCRIPTION

The HI 8751, HI 8752 and HI 8753 electronic thermistor thermometers can measure temperature in the low ranges (-40 to 150°C or -58 to 338°F) with high accuracy.

These thermometers use a miniature silicon sensor and are precalibrated at the factory to measure a wide temperature range without the need to change probes.

This type of sensor is highly accurate with a very fast response time. The sensor is housed in a rugged, stainless steel probe. This probe can be replaced

without requiring recalibration. A wide variety of interchangeable temperature probes (HI 765 series) for measure-

ments in liquids, air and semisolids are available.
