Matters needing attention in the use of portable gas detector
Portable gas detector is mainly used to quickly and accurately detect gas leakage or gas concentration exceeding the standard alarm. The main detection principles of gas detection are electrochemistry, infrared, catalytic combustion, thermal conductivity, PID photoionization and so on. MS104K-L is widely used in fire fighting, emergency rescue, confined space, petroleum, chemical industry, metallurgy, refining, gas, storage, medicine, environmental protection, air treatment and other occasions. So what are the precautions for the use of portable gas detectors?
When using the portable gas detector, you should pay attention to the following points:
1. Regular inspection and calibration: the instrument should be calibrated frequently to ensure that the instrument can actually play its role.
2. Pay attention to the service life of the sensor: different gas sensors have different service life and need to be used within the service life.
3. Pay attention to interfering gases: When detecting a specific gas, pay attention to whether other gases will interfere with the detection of the instrument, resulting in inaccurate detection results.
4. Pay attention to the measurement range of concentration: before testing, it is necessary to estimate the types and concentrations of toxic and harmful gases according to experience, and conduct testing by setting alarm values. When the gas concentration exceeds the detection range of the instrument, it is necessary to turn off the detector to avoid damage to the instrument.
5. Pay attention to the maintenance of the instrument: regularly maintain the instrument and store it in a low temperature environment, which can prolong its service life.
To sum up, when using portable gas detector, it is necessary to operate in strict accordance with the instruction manual to avoid failure or damage caused by improper operation.
