HM-200 Emission Humidity Monitor
HM-200 Emission Humidity Monitor
The HM-200 Humidity Meter is developed based on microprocessor control technology. It is equipped with imported high-temperature capacitive
humidity sensor(CE certified). And it has multiple signal outputs such as 4-20mA,RS232,and RS485. 
HM-200 can be integrated into a CEMS system and installed at the outlet of the sampling heated pipline. It measures the humidity of the sampling flue
gas and upload the data to the CEMS system

Features

  •  CE-certified imported High-Temp temperature and humidity sensor, high precision and stability.

  •  Equipped with a high precision filter to eliminate dust interference.

  •  The unique waterproofing &  dustproofing filter element design, avoiding external interference.

  •  One-key air zero calibration, operation is very convenient.

  •  Full-process high-temp heating, prevent condensation and corrosion of sample gas. Effectively ensure the accuracy and service life of the sensor.

  •   Built-in temperature compensation, which minimizes the impact of temperature changes and ensures high linearity of the measurement.

  •  Can be integrated into the CEMS system, reducing the need for on-site flange openings for measuring humidity


Application

Monitoring and measurement of humidity in flue gas emissions from coal-fired and oil-fired boilers(CEMS), industrial processes, wood production, building materials, papermaking, chemical, fiber,dyeing and printing indus-tries,food processing industries,thermal power plants,and waste incinera-tion plants.
