How to Maintain a Combustible Gas Detector?
1, Regular inspection and calibration
Regular inspection: The alarm should undergo a self check test once a week to check the operation status of the indicator system. At the same time, conduct a visual inspection every two weeks, including connecting parts, movable components, display parts, and control knobs, to ensure that they are not damaged or loose.
Regular calibration: Combustible gas detectors need to be calibrated regularly to ensure the accuracy of their measurement results. The calibration frequency can be determined based on usage and manufacturer recommendations, but it is generally recommended to calibrate at regular intervals or before use.
2, Keep clean and dry
Cleaning sensors: Sensors are an important component of combustible gas detectors and need to be kept clean to ensure their proper functioning. You can use a soft bristled brush, cotton swab, or dry cloth to gently wipe the surface of the sensor to remove dust and dirt.
Keep dry: The combustible gas detector should be placed in a dry and ventilated environment to avoid moisture or water ingress. Wipe the instrument with a dry cloth to prevent moisture or water vapor from entering the inside of the detector.
3, Avoid adverse environmental factors
Avoid blockage: Ensure that the intake and exhaust ports are not blocked to ensure the normal operation of the gas detector.
Avoid high temperature, high pressure, and high humidity environments: It is strictly prohibited to use combustible gas detectors in high temperature, high pressure, and high humidity environments. If the environmental humidity is high, a filtering and dehumidification device should be added.
Avoid chemical corrosion: Do not approach sulfides and silicides such as rubber and silicone around the combustible gas detector, otherwise it may cause sensor poisoning and damage.
4, Correct operation and storage
Correct power supply: Supply power to the combustible gas detector according to technical specifications. Exceeding these specifications may cause abnormal operation or even damage. Use the charger provided or approved by the company to charge the detector.
Handle with care: Avoid hitting or dropping the combustible gas detector to prevent damage. When storing, choose a clean, room temperature place and avoid storing in high or cold places.
Avoid operating beyond the range: Avoid using gas beyond the instrument range to shock the sensor, as this can affect the service life and detection accuracy of the alarm, and even cause direct damage and failure of the sensor.
5, Professional maintenance and replacement
Professional maintenance: If the combustible gas detector malfunctions or gives false alarms, do not disassemble it by yourself. It is necessary to contact the company's distributors in a timely manner and have professional personnel carry out repairs.
