  HT-800 Thermo Hygrometer
  
   
  
   The 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
