Tips: Common faults of ozone gas detector.
- If the ozone gas detector cannot be turned on, it is because the voltage is too low. The solution method is to connect the power supply or charge in time.
- Indication value of the ozone gas detector is inaccurate, which is caused by the long-term uncalibrated detector and the sensor overtime. The solution is to replace the sensor.
- When there is no O3 gas, interface of the ozone gas detector displays a value, which is caused by the drift of sensor, so the zero point calibration should be carried out in time.
- If the normal detection interface of the ozone gas detector displays full scale, it is caused by a sensor failure. Replace the sensor in time
- If the sensor of O3 gas detector drifts too much and the zero point calibration function is not available, the sensor should be calibrated or replaced in time.
- Ozone gas detector does not respond to the detected O3. The possible cause is a circuit failure or the end of the life of the sensor. The treatment method is timely maintenance.
