gas detectorIt is mainly a tool for detecting gas leakage concentrations and has a wide range of applications. Let's share how to use Gas Detector:
First, the principle of periodic calibration
gas detectorSimilar to other analytical detectors, they are determined by the theory of relativity. During the measurement process, the instrument is calibrated with zero gas and standard gas (standard concentration gas) to obtain the standard concentration curve. Then, when measuring special gas concentrations, the electrical signals produced by the gas concentrations are compared with those previously measured at the same standard concentration. After analysis and calculation, accurate gas concentration values can be obtained, so the equipment needs to be calibrated and tested regularly.
2. Mutual interference detected by sensors
gas detectorEach sensor in the sensor will have a special gas corresponding to it. In the selectionGas sensorIt is necessary to fully understand whether the detection of other gases will cause obvious interference to the sensor, so as to effectively ensure the accuracy of the gas detector for special gases. In addition, before using various sensors, standard gases can be used to detect the response of the instrument to ensure its proper operation.
Third, the gas concentration measurement range
The concentration detection range of different types of toxic and harmful gases is different, so that gas detectorNormal working can work normally, and measurements are accurate within this range. On the contrary, if the equipment is measured within the range of gas concentration exceeding the standard for a long time, it is easy to cause serious damage to the equipment and reduce the service life of the equipment.
