Maintenance of the body detector to detect body concentration
The working environment of combustible gas detectors is relatively harsh, and many are installed outdoors. Poor maintenance will lead to errors or non-detection of the body alarm. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent failures.
The grounding should be tested regularly. If the grounding does not meet the standard requirements, or is not grounded at all, it will also make the flammable gas detector susceptible to electromagnetic interference and cause malfunctions.
It is recommended to test the response of the standard gas used for the instruments before using them to ensure that the instruments really play a protective role. Combustible gas alarms and toxic gas alarms, like other analytical and testing instruments, are measured by relative comparison method: first, a zero gas and a gas with a standard concentration are used to calibrate the instrument, and the standard curve is obtained and stored in In the instrument, when measuring, the instrument compares the electrical signal generated by the gas concentration to be measured with the electrical signal of the standard concentration, and calculates the accurate gas concentration value. Therefore, zeroing the instrument at any time and calibrating the instrument frequently are the tasks to ensure the accuracy of the instrument measurement.
The gas detector can continuously and quickly detect the gas concentration in the surrounding environment or in a confined space. The instrument has the advantages of fast response, high measurement accuracy, good stability and repeatability, and the performance of the whole machine is at the leading level in China. The shell of the instrument is made of high-strength engineering plastics. The appearance design and dazzling color matching redefine the detection method of gas concentration; in addition, the friendly operation interface and the recovery function of misoperation bring users a new level of intelligent gas detector. experience.
