Why gas detectors regularly calibrate calibration

The gas detector is an instrument instrument for detecting the concentration of a gas leak. It mainly uses a gas sensor to detect the type of gas present in the environment. The gas sensor is a sensor for detecting the composition and content of the gas. It is generally believed that the definition of a gas sensor is based on the classification of the detection target. That is, any sensor used to detect the composition and concentration of gas is called a gas sensor, whether it is a physical method or a chemical method.

In order to use it more safely, gas detectors need to do regular inspections, whether it is a gas detector or toxic gas detector.

For example: Carbon monoxide detector, some customers do not understand, bought the instrument is not how to use, how to check the verification after a year, the sensor is not the result of the test is not accurate or failure failure it? In fact, this is a normal phenomenon. The heart of the carbon monoxide detector is the sensor, because the sensor's lifespan is counted down since its first day of production. Even if you do not use the carbon monoxide detector, it will take you three months or six months. Monthly or 1 year time to do calibration test, or replace the sensor (some sensors have a life of about 1-2 years).

All gas detectors use a relative measurement method, so they all require timely maintenance and calibration. Only when the manufacturer's requirements are corrected at any time, can the expected accurate results be obtained. The place where such verification can be done is the National Institute of Metrology, and it can also be sent to the manufacturer's domestic after-sales service department. The report they issued is different, but they can all make the instrument work properly.

Additional notes:

1. The gas detector is explosion-proof explosion-proof equipment. Do not use toxic gas alarms beyond the specified range.
2. The detector breather cover should be removed for cleaning when the instrument is inspected to prevent clogging.
3. To make reasonable use of portable gas alarms, time-testing components, and to allow them to expand their usage under conditions of reasonable use and proper maintenance, the detectors should always be checked for accidental incoming toxic gas alarms.
4. The detector must not be used in the presence of sulfur. The detector should be used as far as possible under the condition that the concentration of combustible gas is lower than the lower explosion limit. Otherwise, the device may be burned out.
