The HOM-400 Oxygen & Humidity Monitor adopts the advanced solid electrolyte ceramic sensor technology for measuring current limit method. The core sensor is designed with a high-temperature resistant structure, with a maximum operating temperature of up to 500°C. The product is featured with high-temperature resistance, high measurement accuracy, strong corrosion-resistance, fast response, and stable and reliable performance. It is particularly suitable for continuous online measurement of humidity and oxygen under harsh working conditions such as heavy metals, high corrosion, high humidity, and organic interference in VOCs.


Features

  •   Simultaneous online monitoring of humidity and oxygen.

  •   The sampling detector is equipped with a self-heating function, which prevents the sample gas from condensing.

  •  Multi-stage high-precision filtration, effectively prevents the interference from dust or other substances.

  •  High mechanical and electrical protection ratings, strong resistance to the interference.

  •  Directly installed through the flange opening on the chimney, it can more intuitively reflect the concentration of the flue gas.

  •  Built-in high-temperature resistant sensor. Suitable for high-temperature working condition.

  •  Corrosion-resistance sensor. Longer service life in the field.

  •  Serial port screen communication. Easy to operate and maintenance.


Application

  •  Continuous emission monitoring system (CEMS);

  •  Wood, construction materials, papermaking industry;

  •  Chemical industry, fiber industry, dyeing and printing industry;

  •  Food processing industry;

  •  Thermal power plants, waste incineration plants;

  •  Harsh working conditions, eg. heavy metals, high corrosion, high humidity, and organic interferences in volatile organic compounds (VOCs).
