Maintenance specifications for gas detectors 次测量时不至于影响检测结果。 When using the gas detector, industry personnel must pay attention to the maintenance of the gas detector at the same time. This will increase the service life of the instrument and will not affect the test results during the next measurement.
There are the following points for the maintenance specifications of the gas detector: 1 Regular inspection, calibration and impact test of the detector. 2 Maintain a record of all test, calibration, and alarm events. 3 Keep the surface of the instrument dry and clean, away from wet, rain and corrosive gas and liquid. 4 Keep away from dust and keep the surroundings clean. 5 The ambient temperature is moderate and should not be too high or too low to prevent affecting electronic components. 6 Knock, shake or drop the instrument violently. 及时擦干。 7 Irritating chemicals, detergents or cleaners with a high concentration are also prohibited. It is feasible to wipe the instrument with a soft cotton cloth dipped in a little water, and it needs to be dried in time. ,使液体自行流出。 8 The detection hole of the instrument should be wiped frequently to keep the piping of the hole unblocked and avoid liquid flowing into the detection hole. Once the liquid flows in , place it downward and let the liquid flow out by itself. 9 For air leakage in the gas system, check whether the diaphragm of the suction pump is damaged, and check whether the seal ring is broken. Whether the condensate and four-way valve are damaged. 10 The flammable gas alarm prompts to replace the filter paper, stop the suction pump, and filter out the drainage in the tank. 11 Note the detection interference between various sensors. 年或更长；LEL传感器的寿命一般可以使用三年左右；氧气传感器的寿命大概在一年左右。 12 Note the life of various sensors The life of electrochemical specific gas sensors is generally one to two years; the life of photoionization detectors is four years or more; the life of LEL sensors can generally be used for about three years; About a year or so. 延长一定的使用寿命。 Cryopreservation can extend a certain service life. 13 The flow rate of the test gas is usually 30 / h. The value cannot be too large or too small, otherwise it will affect the result.
的浓度测量范围：只有在其测定范围内完成测量，才能保证仪器准确进行测定。 Pay attention to the measuring range of the concentration of the testing instrument : Only when the measurement is completed within its measuring range can the instrument accurately measure.
