HT-800 Thermo Hygrometer

HT-800 Thermo Hygrometer

Thermo HygrometerThe HT-800 Thermo Hygrometer has been designed with a highly reliable polymer film humidity sensor. The HT-800 Thermo Hygrometer is equipped with unique features such as a high stability, good repeatability and fast response order to keep high accuracy of measurement at bad ambient. Platinum resistance element (PT100W) is used for temperature measuring and compensation. The HT-800 Thermo Hygrometer has its own dual display which continuously indicates %RH and Temperature simultaneously in ºC or ºF, data hold, power exhausted signal and probe connection can be shown on the display, especially dual analog output can be accessed for controller, recorder or P/C system expansion.

Thermo Hygrometer Features:

  • Dual analog output of temperature and humidity for system expansion

  • Unique LCD dual display which continuously indicates temperature and humidity simultaneously

  • Compact interchangeable combined temperature/humidity probe

  • High stability, non-calibration before using

  • ºC/ºF switchable

  • High accuracy, Temperature: +/-0.2ºC Humidity: +/-2.5%RH

  • One touch "Data-Hold" function

  • High precision "Macromolecule Humidity Sensor" with quick response and no hysterisis

  • Water resistant design, easy operation
