HM-100 High-temperature Hygronom


Hygronom is also called gas moisture meter or dew-point meter, which is used to measure the humidity of flue gas emitted by pollution source. According to measured humidity, it converts wet gas concentration into dry gas concentration. In addition, it also can be used in industrial online humidity monitoring.


HM-100 flue gas hygronom is equipped with an internal high-precision capacitance digital temperature & humidity sensor. The installation method adopts the in-situ immersion installation. It is a self-developed product, of which, the core component is from Switzerland. Put the sensor inside stack to get in touch with flue gas. The probe needs preheating to prevent gas from condensation, which will affect the measurement of moisture in the flue gas. After gas contacts with the measurement chip, the chip will change capacitance to measure flue gas concentration.


Features Of HM-100 High-temperature Hygronom


• The product is convenient for installation, disassembly, and cleaning with small and compact structure

• Direct and simple key operation on site

• The probe is equipped with heat tracing function to prevent condensate water from damaging humicap and thermal resistance

• Imported core components with high-performance index and reliability
