in a large number of gas detection equipment, combustible gas detector has always been a kind of application more, when the concentration of combustible gas exceeds the value specified by the state, combustible gas detector sound and light alarm, and according to the field linkage fan, to avoid accidents. Therefore, in order to better use the combustible gas detector, we should do its maintenance work. So how should we maintain combustible gas detector ? The following is a brief introduction by Yiyuntian:

The maintenance of combustible gas detector should be done well:

1. do not overcharge for a long time (avoid wrong inspection)/

try to avoid one-time long in daily life time to charge, when charging, the combustible gas detector should be placed in a shutdown state, which can reduce the charging time and extend the life of the detector. Because the combustible gas detector is charged in the power-on state, the sensor of the instrument may be affected by the charger, resulting in sudden alarm or gas error detection.

2. pay attention to regular charging when idle

combustible gas detectors are used less frequently in many places, in the daily directly let the instrument idle, which not only will not play a maintenance role, but also reduce the life; in the idle state should be an interval of 2 to 3 months on the combustible gas detector for a charge, in order to protect the normal life of the battery.

3. Prevent frequent impacts and falls

The combustible gas detector must be placed in a safe position in daily life, when detecting in special places, the position should be selected before detection. Although the external casing of the combustible gas detector has the function of resisting external force, frequent collision, impact or fall will reduce the accuracy of the detector and cause irreversible damage.

4, keep the combustible gas detector dry

, all products, including combustible gas detectors with higher protection levels, should avoid contact with water sources. Keeping combustible gas detectors dry is a key step to extend their service life. This requires the user to use a dry cloth when wiping the combustible gas detector to ensure that the interior of the combustible gas detector will not enter moisture or water vapor, effectively avoiding damage to the circuit of the detector and affecting the accuracy of the alarm.

5. prevent touching with water source (products with higher protection level should also be prevented)

many operators will use a damp rag, scrubbing the screen or external casing of the combustible gas detector is an illegal maintenance behavior, because once moisture or water vapor enters the detector, the detector circuit will be damaged and the alarm accuracy will be affected. Similarly, the combustible gas detector cannot be touched with corrosive substances, which will also cause certain damage to the detector.

In summary, some aspects of the maintenance of the combustible gas detector should be done well. In order to effectively ensure the reliability of the testing instrument, it is necessary to prevent the failure caused by the aging of the combustible gas detector components, and the combustible gas detector that is used for an extended period must be replaced in time.Moreover, in different application places, different combustible gas detectors should be selected. The use of coal gas, natural gas, liquefied gas places should use semiconductor type combustible gas detector, and the emission of combustible gas, combustible steam industrial places are good to use catalytic combustible gas detector.
