As we all know, high-precision gas detectors can quickly respond to and capture small changes in gas concentration, so as to provide users with reliable data support, help users make correct decisions in time, and effectively prevent potential safety hazards. It can be seen that improving the accuracy of the gas detector has undoubtedly become a vital part of ensuring its effectiveness. It is directly related to the accuracy and safety of the monitoring work and is an indispensable part of ensuring the smooth operation of the production environment. So do you know how to improve the accuracy of gas detector ? The following is a brief introduction to yiyuntian electronics:

The methods to improve the accuracy of gas detector mainly include the following aspects:

1. high-performance sensors

Select the appropriate sensor: the gas detector should select the appropriate sensor according to the type of gas detected, because different sensors may have different detection accuracy for different gases.High-performance sensors should have the characteristics of high sensitivity, good selectivity and strong stability.

Consider the life of the sensor: The gas detector should choose a sensor with a longer service life to reduce The accuracy of the sensor is reduced due to aging.

2. optimization environment conditions

Control temperature and humidity: gas sensors are very sensitive to ambient temperature and humidity, so ensure that the gas detector works under suitable temperature and humidity conditions.Generally, the temperature range should be controlled between -20°C and 55°C, and the humidity range between 15% RH and 90% RH (60% RH at a suitable humidity of 20°C). The method of temperature and humidity compensation can be used to reduce the influence of temperature and humidity on the measurement results.

Manage gas pressure: ensure that the gas measured by the gas detector sensor is blown parallel to the top surface of the sensor, instead of blowing vertically to the top surface of the sensor, and ensure that the pressure inside and outside the gas chamber is the same to avoid the influence of pressure changes on the measurement results.

Reduce electromagnetic interference: avoid using gas detectors in environments with strong electromagnetic interference, so as not to affect its normal work and detection accuracy.

3. correct installation and operation
