Feature

Semiconductor heating type - qualitative detection.
With analog and TTL level signal output.
Analog output voltage with the concentration is not a linear relationship ,you need to convert the analog voltage into the resistance ratio, and then calculate the specific concentration value through the logarithmic relationship.
The test concentration range of gas-sensitive elements : 10 to 1000ppb.
Application:Mainly used for qualitative determination, suitable for home, environmental gas detection equipment, suitable for the detection of ozone gas.
