Scope of application:

It is suitable for the detection of bidirectional gas in underground engineering such as coal mine, underground pipeline, tunnel, etc. It is also suitable for the detection and alarm of toxic gas and vapor leakage in explosion-proof places and chemical, municipal, fire and other toxic and harmful gases and vapors.

Daily use precautions:

In order to ensure the high efficiency of the gas detector in the industry, users should pay attention to:

1, regular calibration, it is generally recommended that 6 months or 12 months to calibrate the instrument, the use of standard gas to calibrate the instrument, in accordance with the instrument operating instructions, in the absence of accurate target gas, do not adjust at will.

2, the gas detector sensor drift problem, this is an inherent characteristic, no matter how precise it is a meter, the sensor will have a trace of zero drift every month, so the need for zero calibration.

3, the gas detector sensor has different preheating time due to different principles, so in order to ensure the best performance, it is necessary to start preheating in advance.

4, the gas detector is mainly to detect the concentration of gas, so the sensor components must not be water.
