combustible gas alarm is currently widely used in some places where there may be combustible gas leakage and the use of gas detection instruments, so that it can effectively protect the concentration of combustible gas in the air to reach the critical point of explosion or poisoning alarm set, alarm. However, in the process of using combustible gas alarm, we sometimes encounter errors in the detection results of combustible gas alarm. Then do you know what causes the error in the detection result of combustible gas alarm ? The following is a brief introduction by yi yun Tian:

Combustible gas alarm detection results error, mainly caused:

1. Impact of environmental factors

There may be gases in the environment that cause sensor poisoning or inhibition (general users may not know what gases cause sensor poisoning or inhibition); dust or soot in the environment will block the detector probe, so that the sensitive element can not contact the combustible gas, resulting in the sensor response is not sensitive or no response.The installation position of combustible gas alarm often has water vapor, water droplets, humidity, etc., which will reduce its performance or damage. The combustible gas alarm detector installed outdoors will be insensitive when the temperature is lower than the allowable temperature in winter, and the rain and snow prevention measures are not good. Water inflow will lead to instrument failure or damage.

2. Uncertainty of testing site
