gas detector, as a precision instrument for detecting the gas concentration value in the air environment, when the flammable or toxic gas in the environment leaks, and the gas detector detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the alarm will send out an alarm signal to remind the staff to take safety measures. In the process of using the gas detector, sometimes there will be a large error in the display of the gas detector, and the emergence of this situation will undoubtedly have a certain impact on the detection work. Then gas detector how to solve the large display error? The following is a brief introduction by yi yun Tian:

Possible causes of large display error of gas detector:

The longer the sensor of the gas detector is used, the more frequently the measured gas appears in the use environment, or the detector works in a high temperature and high humidity environment, the linear attenuation of the sensor will occur, resulting in an increase in the indication error.

The solution to the large display error of the gas detector:

the gas detector has a large display error. for handling such faults, standard gas needs to be introduced and calibrated according to the manufacturer's instructions. if the standard gas concentration cannot be reached through calibration, the sensor is judged to be invalid and a new sensor needs to be replaced.

if the reaction is slow or no reaction occurs after the gas is introduced, first check whether the air hole of the sensor assembly is blocked, the air inlet channel of the detector is blocked or the air inlet channel is blocked due to debris around it, which slows down the reaction of the hydrogen sulfide gas detector and reduces the sensitivity. If there is no blockage, analyze the cause of the failure as aging or failure of the internal sensor of the detector, and replace the sensor.

To sum up, it is the possible cause of the large display error of the gas detector and the related solutions. In order to effectively ensure the measurement accuracy of the gas detector used, the user department should regularly send the sensor to the professional department for calibration to ensure that the gas detector used on site can accurately obtain the gas concentration value in the air environment and avoid the occurrence of toxic and harmful gas leakage accidents.
