Solutions to inaccurate gas detector detection

 

Gas detection is a very important procedure for many factories, as many production processes require the use of potentially toxic gases and some processes may produce hazardous gas by-products. If regular equipment maintenance and inspection monitoring can be carried out, this danger can be detected early and controlled within a small range.


Solution:
1. Confirm whether the gas concentration on site is accurate. Sometimes there is a large difference between the theoretical value and the actual value. Verify the accuracy of the instrument by introducing standard gas or sending it to a third-party measuring institution for testing.


2. If the sensor has been used for a long time, there may be some measurement errors. It is necessary to confirm with the manufacturer whether the sensor can still be used before continuing to use it. If the sensor itself is approaching its service life, even if it can be used normally after calibration, it will not be able to be used normally for long. It is recommended to replace the sensor.


When the value is 0 or the alarm value is not reached in the air, it will also sound an alarm.


resolvent:
1. Check if the alarm value has been modified.


2. Check the alarm method and whether the alarm mode has been modified.


3. Check whether the alarm status is concentration alarm or fault alarm. The concentration alarm will display the words AL or AH, and the red indicator light will flash. The fault alarm will light up the yellow light.


4. If the alarm is caused by human modification, it can be resolved by restoring the factory settings. The fault alarm needs to be further checked for short circuit, open circuit, poor contact, sensor failure, etc., or sent back to our company for testing.
