Combustible gas detection maintenance and environmental requirements
Although combustible gas detectors are generally suitable for various harsh environments, it does not mean that there are no requirements for the working environment. What are the requirements for the working environment of combustible gas detectors? What maintenance and upkeep are needed?
1. Due to the generally harsh working environment of combustible gas detectors, polluting gases and accumulated dust may enter the interior of the instrument. Therefore, it is necessary to regularly clean and maintain the combustible gas detector to improve its accuracy and sensitivity.
2. In order to ensure that the gas detector is not affected by electromagnetic interference, it is necessary to test the grounding of the instrument to prevent situations such as ungrounded or substandard grounding.
3. Ensure the reliability of the instrument and prevent malfunctions caused by aging of instrument components. Systems that have exceeded their service life should be replaced in a timely manner.
4. Different gas detectors should be selected for different application scenarios. Semiconductive combustible gas detectors should be used in places that use coal gas, natural gas, and liquefied gas, while catalytic combustible gas detectors are preferred in industrial places that emit combustible gases and vapors.
Precautions for daily use of portable gas detectors
1: Portable gas detector can detect under normal working environment, and the sensor has a working life of more than two years
2: Prevent portable gas detectors from falling from heights or being subjected to severe vibrations
3: If the machine shows no response for a long time, please turn off the power of the portable gas detector and restart it
4: Portable gas detectors should be used in places that are free of corrosive gases, oil fumes, dust, and rainproof
5: To ensure measurement accuracy, portable gas detectors should be calibrated regularly, and the calibration cycle should not exceed one year
6: Do not allow portable gas detectors to frequently come into contact with high concentration gases above the detection range, and it is strictly prohibited to collide and disassemble the sensor, otherwise it will lose the working life of the sensor
