Effect of AN-002 Ventilation Humidity on NDIR LARK-1 CH4 Reading 17-07-12
The specifications of NDIR gas sensors generally give the range of humidity, defined as relative humidity% RH, which means that the range of humidity can be determined. Ensure the humidity range of NDIR sensor working normally. High humidity does not damage the sensor without producing condensate. But it will cause the reading error of the sensor. In the case of methane, for example, the reading will generally be higher when the humidity is high. To study ventilation humidity The influence of degree on the reading of NDIR LARK-1 CH4 sensor. We use LARK-1 CH4 sensor to access different humidity standards. The humidity experiment of the gas was carried out, and the experimental data were analyzed and summarized.
