Does the newly purchased gas detector need to be tested?
Gas detection is a very necessary task for safety protection. Gas detectors can effectively ensure gas detection in limited spaces and ensure the safety of the space. But many users will have a question, that is, does the newly purchased gas detector need to be tested?
No, the gas detector will undergo strict testing before leaving the factory, and all indicators will be well controlled. Users can use it after receiving the instrument and following the instructions. Since the gas detector will undergo certain losses during use, it needs to be regularly tested at least once a year after use to ensure the accuracy of the gas detector, avoid false alarms, false alarms, etc., and ensure production safety as much as possible .
The gas detector can be tested every 3 months, 6 months or a year depending on the location of use, frequency and other factors. It mainly includes the measurement performance, appearance structure, whether the connection is reliable, whether the signs are clear and complete, and whether the sound and light alarms are Whether it is normal, etc. The measurement performance mainly includes indication error, repeatability, response time, drift degree and other indicators for testing, mainly to ensure the accuracy and response speed of the instrument. The appearance of the gas detector should not be damaged that would affect normal operation. The surface of the new instrument should be smooth and smooth, with uniform paint color and no peeling, rust, etc. The instrument name, model, manufacturer name, factory date, serial number, explosion-proof mark, etc. should be complete and clear. The sound and light alarm of the gas detector should respond normally. In addition, it needs to be tested in an environment of 0-40°C, a relative humidity of less than 85%, and no interference with the gas being measured.
The gas detector mainly detects gas through the internal gas sensor. The sensor has a service life. You need to ensure that it is used within the validity period of the sensor. Do not use it after the validity period. The life of the common catalytic combustion type is 1-3 years, the electrochemical type is about 2 years, the PID is about 2 years, and the infrared can be used for 3-5 years.
