How much time is remaining on the gas detector?
How long is the validity period of the gas detector? The gas detector can basically be used for 1-3 years, and the longest service life can reach 5 years. There are different use time limits according to different situations. The service life of the gas detector actually refers to the service life of the gas sensor, the core component of the instrument, and the service life of sensors with different detection principles is also different. Therefore, the use time limit of a gas detector is related to the type of internal gas sensor, frequency of use, and on-site working conditions.
Generally, the service life of catalytic combustion sensors will be longer, about 3 years. The service life of the electrochemical sensor is about 2 years, the service life of the PID photoion sensor is about 2 years, and the infrared sensor can basically be used for about 3-5 years. During use, the gas concentration in the environment, on-site environment, sensor response frequency, etc. will all affect the validity period of the detector. In addition, it should be noted that the detector needs to be calibrated by a professional verification institution every year to ensure the accuracy of the instrument.
The on-site environment has a great influence on the service life of the gas detector, and the gas concentration, temperature, pressure, humidity, etc. in the environment will affect its service life. The lower the gas concentration in the environment to be tested, the less the response frequency of the gas detector and the longer the service life. The higher the concentration of the gas to be tested, the higher the reaction frequency of the gas detector, and the more obvious impact on the life. Wear and tear, resulting in reduced useful life. Excessive pressure in the environment will cause a pressure difference between the inside and outside of the instrument, which will compress the gas detector components. Too high or too low temperature will affect the electrolyte in the gas sensor and affect the life of the sensor. Excessive humidity will also damage the internal parts of the gas detector, corrode metal parts, and affect the service life of the detector.
