article image 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.

According to Hanna Instruments , temperature measurements in the low ranges (-40 to 150°C or -58 to 338°F) are usually performed with thermometers that use the physical expansion of liquids such as in glass and dial thermometers.

In terms of accuracy, these thermometers usually read within ±1 to ±5°C (±2 to ±9°F) of the actual temperature. In order to achieve higher accuracy, the range must be reduced or the length of the thermometer must be increased. The HI 8751, HI 8752 and HI 8753 electronic thermistor thermometers resolve these problems. 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 measurements in liquids, air and semisolids are available.

HI 8751 is supplied complete with HI 765PW temperature probe with 1 m (3.3’) cable, battery and instructions.
