I believe everyone knows that gas stations must install gas station combustible gas alarm to detect the concentration value of flammable gas at all times. This is mainly because the gas station contains gasoline with flammable and volatile characteristics. Once these combustible and toxic gases leak, the consequences will be disastrous. Therefore, in order to better ensure safety, it is necessary to regularly calibrate the combustible gas alarm of the gas station. Do you know how to calibrate the gas station combustible gas alarm ? The following is a brief introduction by yi yun Tian:

gas station combustible gas alarm calibration method:

1. In principle, the standard sample gas matching the tested gas shall be used for the calibration of combustible gas alarm at gas stations. The same measured medium selected standard gas is different, the alarm point is also different.

2. Before calibrating the combustible gas alarm of the gas station, there should be no combustible gas in the surrounding environment of the probe. If there is combustible gas, remove the rain cover first, fill a certain amount of clean air, and then continuously introduce sample gas to ensure the accuracy of calibration.

3. when the measured gas of the combustible gas alarm of the gas station is hydrocarbon mixture, isobutane is the sample gas, followed by propane.

4. for hydrocarbon mixtures with a large difference in heat generated during combustion of non-hydrocarbon mixtures or gases with lower explosive limit concentration, butane, isobutane, propane and other easily available and stable single-component fuels can be used as sample gases when necessary.At this time, the combustible gas alarm of the gas station must adjust the range of the alarm according to a certain conversion relationship of the detection signal.

In summary, it is the calibration method of the gas station combustible gas alarm. In a word, the calibration of gas station combustible gas alarm is a professional and rigorous work, and a little operation details can not be ignored. Therefore, we must pay special attention to the calibration of gas station combustible gas alarm.
