Fixed Carbon Monoxide (CO) Gas Detector Details

Tips: Working Principle of Gas Detector Sensors

  1. Electrochemical Sensors
    Due to the active chemical properties, the testing gases generally have reducibility or oxidizability. Electrons are released or absorbed in the chemical reactions and a large number of electrons form a current. The current is proportional to the gas concentration, thus the gas concentration is obtained by measuring the current.
  2. Catalytic Combustion Sensors
    It works based on the principle that the heat is released from the combustion reaction of a surface combustible gas, namely combustion increases the temperature of the platinum wire coil and thus the resistance of the coil increases. The gas concentration is obtained by measuring the resistance value change of platinum wire. It’s suitable for measuring low concentration combustible gas.
  3. PID Photo Ion Sensors
    High energy ultraviolet rays ionize the organic gases, and then amplify the current of charged ions on the plate to measure. The current value reflects the gas concentration.
  4. Infrared Sensors
    Different combustible gas has different absorption ability to infrared ray. The concentration of combustible gas can be measured by detecting the current on the infrared photosensitive component.
  5. Semiconductor Sensor
    Due to the absorbability of semiconducting materials on gas, change the resistance value of the gas sensitive resistance to judge the existence of gas.

CO gas detector resolution
I’m looking for a fixed CO gas detector for my basement. I need 0-500ppm measuring range and I want to know what the resolution of your detector is in this range.

Hi, my friend. The resolution of 0-500ppm is 0.1ppm.
Works so good.
We bought this carbon monoxide detector as we have to monitor the CO exposure in the well. The detector arrived in time and was easy to install. So far, the detector gave us twice alarming. Works so good.
