Model: HT-1
Product number: HT-1A (no alarm function)
HT-1B (with alarm function)

1. Function:
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; Millions of dollars could be saved in time.

2. Features:

2.1 Calibration reminding: In order to help complying with the regulation of ISO, a unique design of calibration expiration reminding function is offered in HT-1. When the sensor runs over 365 days, the decimal point in the panel will be flashed for reminding the user.
