Combustible gas alarm has been widely used in many industries. It can detect the leakage in dangerous places. At the same time, the personal and property safety of the staff in the place can be fully guaranteed to avoid a series of problems such as environmental pollution, casualties and property losses. So is Combustible Gas Alarm required for the verification of environmental conditions? The following is a brief introduction by yi yun Tian:

because the combustible gas alarm is the 1 electronic instrument, the error in the verification mainly comes from the verification environment, so the requirements for the verification environment conditions are as follows:

1. Good ventilation is required.

For open combustible gas diffusion and escape, if there is no good ventilation condition, it is easy to make the combustible gas content in the air of a certain part approach or reach the lower explosive limit concentration, resulting in inaccurate verification results.

2.

Pay attention to electromagnetic interference during the verification of combustible gas alarms.The influence factors of electromagnetic environment on combustible gas alarm mainly include the following 3 aspects: human body static electricity, narrow pulse group on power supply and other input and output lines, and electromagnetic wave interference in the air.

3. Ambient temperature.

In the process of verification, the change of temperature before and after detection will significantly change the vitality of molecules, and the increase of temperature will increase the risk. The temperature has no direct effect on the combustible gas alarm itself, but below 0 ℃, the inertness of the standard gas is enhanced, and the activity of the standard gas molecules is not active enough. When the temperature is low, the instrument display value will have a great error, and the temperature is below 0 ℃.

To sum up, it is the requirement of combustible gas alarm for verification of environmental conditions. As there are many kinds of gas alarms on the market at present, and combustible gas alarms produced by various manufacturers also have different characteristics, the inspectors should carefully read the product instructions before using them to understand the basic information involved in the detection such as the working principle, measuring range, alarm point, detection/calibration gas of combustible gas alarms, as well as the precautions for operation and use, so as to better ensure the smooth progress of the detection work.
