Tips: Maintenance of nitrogen gas detector.

1. Regularly calibrate, test and inspect the nitrogen gas detector. In general, the calibration frequency is once a year.
2. As the most important part of nitrogen gas detector, the sensor should avoid exposure to the gas generated by inorganic solvents or organic solvents as much as possible. Especially for electrochemical sensors used to detect toxic and harmful gases, the evaporation or contamination of the electrolyte will cause the signal of the sensor to drop and shorten the service life of the N₂ gas detector.
3. When installing the nitrogen gas detector, please do not put it close to the wall, and reserve enough space around it for daily maintenance and troubleshooting.
4. Ensure that the nitrogen gas detector is in a dry state to avoid affecting its detection accuracy and service life due to the humid environment.
5. The entire outside of the nitrogen gas detector needs to be kept clean. You can wipe the surface with a soft damp cloth. Do not use a damp cloth dripping with water to prevent water droplets from accidentally splashing into the N₂ gas detector.
6. Dust cover of the sensor is for protection. In order to prevent the dust cover from being blocked by dust and affecting the use of sensor, it should be cleaned regularly.
