The gas detector is a kind of instrument and instrument tool for gas leakage content monitoring, including portable gas detector, fixed gas detector, etc. The gas sensor is used to monitor the gas content in the environment. The gas sensor is used to monitor the composition and content of the gas.
The gas detector can monitor the leakage of gas, and use the audible and visual alarm system to remind everyone to implement safety protection measures such as personnel evacuation, forced ventilation, and shutdown of equipment. It is an indispensable instrument and equipment in industrial manufacturing and daily life.
However, the gas detector can not always accurately measure the gas content. Just as our watches need to be calibrated regularly and at standard time, the gas detector also needs to be calibrated regularly to ensure the accuracy of monitoring, and the calibration process is called "calibration".

Why calibration

The accuracy of the combustible gas alarm is the main premise for monitoring and sending out the alarm, and its accuracy lies in that the built-in combustible gas sensor, whether electrochemical sensor or catalytic combustion sensor, will be interfered by some substances in the environment during the application process, and will slowly change and even fail. It needs timely maintenance and calibration to ensure the accuracy of the results detected by the instrument.
In practical application, many factors will interfere with the accurate value of the alarm. Periodic calibration is to better reduce the error of the monitoring results to the minimum and achieve the highest accuracy.
