What issues should be paid attention to when using combustible gas detectors?
The main function of a combustible gas detector is to check whether the concentration of combustible gases in the air has reached a certain dangerous value. When the concentration of combustible gases in the air reaches a certain level, the combustible gas detector will automatically sound and light an alarm, reminding people to take corresponding measures in a timely manner to prevent major incidents and ensure the safety of the company's production and the lives of operators.
Combustible gas detector is one of the commonly used safety equipment in chemical enterprises. Besides paying attention to daily maintenance, there are always some issues that are overlooked during use.
The application of combustible gas detectors or portable combustible gas detectors in oxygen deficient atmospheric environments may result in combustible gas displays lower than the actual concentration. On the contrary, using a combustible gas detector in an oxygen rich environment may result in a reading of combustible gas that is higher than the actual concentration.
When the combustible gas report concentration meter is displayed, the combustible gas sensor should be recalibrated. For example, in the process of using a combustible gas detector, the detection range of the equipment is 0-100% LEL. When the actual concentration is higher than 100%, it will cause the range to be too large. At this point, it is necessary to calibrate the gas sensor again.
3. The water vapor or other known impurities of silicon compounds may affect the normal operation of combustible gas detectors, resulting in readings lower than the actual gas concentration. If the instrument is used in a water vapor environment for silicon compounds, please recalibrate the instrument before the next use to ensure measurement accuracy.
