The application of gas detectors is extremely widespread, visible in our daily lives everywhere. Have you been using them correctly?
1. The concentration range for the gas detector
Prior to testing, it is necessary to estimate the gas concentration based on past experience, and then use a gas detector for the measurement. If the estimated gas concentration exceeds the instrument's detection range, the device should not be used, as over-range testing can cause severe damage to the instrument, potentially leading to the instrument being rendered unusable.
2. Life span of gas detectors
Gas detectors with different types and designed to detect various gases have varying service lives. When selecting, pay attention to the instrument's service life, whether it's within the warranty period, and if not, a gas detector that has exceeded its warranty or service life cannot effectively detect toxic or harmful gas concentrations accurately.
3. Calibration and Maintenance Before Using Gas Detectors
Long-term storage of instruments can affect their accuracy due to factors like temperature and humidity. Therefore, calibration is essential before use. During regular storage, gas detectors should be kept in a low-temperature, dry, and sealed environment to extend their lifespan.
4. Certain gases interfere with the test results.
Typically, businesses use a single gas detector to monitor specific gases. Sometimes, the environment where the detector is placed is complex, containing a variety of gases. In some cases, other gases with similar physical and chemical properties to the target gas (O2 & O₃) can be produced, which may interfere with the detector's results.
