HM-200 Hygronom
#precision #humidity #meter\Overview Of HM-200 Precision Humidity Meter
Hygronom is the professional humidity meter used to measure the humidity of flue gas emitted by pollution sources. According to measured humidity, it converts wet gas concentration into dry gas concentration. In addition, the HM-200 precision humidity meter also can be used in industrial online humidity monitoring.

HM-200 hygronom (online precision humidity meter) is an intelligent humidity/ oxygen transmitter, which employs microprocessor as the core, and frequency conversion icon oxygen sensor as a measuring unit. The installation method adopts a heat tracing pipeline installation. The HM-200 precision humidity meter manufactured by ZETIAN, one of the best humidity meter manufacturers, is a self-developed product, of which, the core component is from Switzerland.

Under the effect of the air pump, the flue gas inside the stack enters the measurement module after heating from the heat tracing probe. The whole process of extraction, measurement, and discharge is with heat tracing to prevent gas from condensation, which will affect the measurement of moisture in the flue gas. The flue gas enters the measurement module after heating and the frequency conversion icon oxygen sensor will start to measure gas concentration. After the measurement, the gas can get into an analyzer for the measurement of other components.
