Help Managing the Temperature and Humidity of production Line!

Alarm Hygrometer is installed at precisely controlled environment, such as storage room of precious collections, production line of high tech electronic components, optical and medical industries …etc. It can not only display the temperature and relative humidity, but also alert the engineers to check and repair the facilities immediately by flash or buzzer alarm that is activated as soon as the temperature or relative humidity exceeds the preset tolerance. With this function, millions of dollars could be saved in time. To save monitoring manpower at a huge plant,32 sets of HT series can be connected to a PC through intranet network. All of the data of temperature and relative humidity will be recorded and the fluctuation will be shown in the graph.


  • Calibration reminding: In order to help complying with the regulation of ISO, a unique design of calibration expiration reminding function is offered in HT series. When the sensor runs over 365 days, the decimal point in the panel will be flashed for reminding the user.
  • Superior visibility: Equipped with LED display, the perfect visibility can definitely avoid any ambiguous reading. It is important in many occasions.
  • Cost effective: HT series is very cost effective compare to any existing similar hygrometer in the market.
  • Function upgrade: Advanced functions such as data logger,setting of warning tolerance and central monitoring via intranet can be upgraded to meet the customer’s requirement in the future.
