Precautions for the use of portable multi-gas detectors
Pay attention to the measuring range of the portable gas detector used:
Any gas detector has a fixed detection range, and the measurement can only be completed within this range, otherwise the measured result will be far lower than the value of your environment. In addition, long-term out-of-range measurement will cause damage to the sensor, so that correct results cannot be obtained within the measurement range in the later stage.
Pay attention to the service life of the sensor in the gas detector used:
Gas detectors have a limited service life, and portable gas detectors are no exception. Even if they are not used frequently, they will still experience aging. In general, among portable gas detectors, the photoionization detector has a long lifespan, which is about four years; the LEL sensor has a second lifespan, which can be used for more than three years; the electrochemical specific gas sensor has a relatively short lifespan. Usually one to two years; the oxygen sensor can only be used for about a year.
Therefore, be sure to read the manual before use, and use it within the validity period of the sensor. If it is found to be expired, it needs to be replaced immediately.
