Features

  • Portable structure, easy to install and disassemble
  • Able to measure humidity of 300℃ flue gas
  • Able to match with large-scale system for measurement or independent measurement
  • The probe is equipped with heat tracing function to prevent condensate water from damaging probe and affecting measuring value
  • Imported core components with high performance index and reliability

Hygronom is used to measure 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-200 hygronom is an intelligent humidity/ oxygen transmitter, which employs microprocessor as the core, and frequency conversion icon oxygen sensor as measuring unit. The installation method adopts heat tracing pipeline installation.  It is a self-developed product, of which, core component is from Switzerland.
Under effect of air pump, the flue gas inside stack enters measurement module after heating from heat tracing probe. The whole process of extraction, measurement and discharge is with heat tracing to prevent gas from condensation, which will affect measurement of moisture in flue gas. The flue gas enters measurement module after heating and frequency conversion icon oxygen sensor will start to measure gas concentration. After measurement, the gas can get into analyzer for measurement of other components.
