What should be paid attention to when using a combustible gas detector?

The combustible gas detector is mainly used to detect the concentration of combustible gases at the scene of the accident. It can detect the lower explosion limit concentration (percentage content) of a single or multiple combustible gases and send out an alarm. A qualified combustible gas detector can greatly protect the personal safety of employees and avoid major accidents. So what should be paid attention to when using a combustible gas detector? Let's take a look at it together!

When using a combustible gas detector, pay attention to the following issues:

1. Pay attention to regular calibration and testing.

Like other analytical and testing instruments, the combustible gas detector is measured by a relative comparison method: first calibrate the instrument with a zero gas and a gas of a standard concentration, and obtain a standard curve stored in the instrument. During the measurement, the instrument compares the electrical signal generated by the concentration of the gas to be measured with the electrical signal of the standard concentration, and calculates the accurate gas concentration value. Therefore, zeroing the instrument at any time and calibrating the instrument regularly are essential tasks to ensure accurate instrument measurements.

It should be noted that many gas detectors can replace detection sensors at present, but this does not mean that a detector can be equipped with different detector probes at any time. Whenever the probe is replaced, in addition to a certain sensor aging time, the instrument must also be recalibrated.

2. Pay attention to the concentration measurement range of the detection instrument

All kinds of toxic and harmful gas detectors have their fixed detection ranges. Only by completing the measurement within their measurement range can the accuracy of the instrument reading be guaranteed. If the measurement exceeds the measurement range for a long time, it may cause permanent damage to the sensor. For example, if a combustible gas sensor is accidentally used in an environment exceeding 100%LEL, the sensor may be completely burned. And toxic gas detectors will also be damaged if they are used at a higher concentration for a long time. Therefore, if the combustible gas detector is always in full scale during use, the power supply must be turned off immediately to ensure the safety of the sensor.

The above issues that require attention when using combustible gas detectors are shared here. Combustible gas detectors are widely used in hotels, restaurants, gas stations and other places where gas leaks may occur. Qualified combustible gas detectors can greatly protect the personal safety of employees and avoid major accidents.
