What aspects of a gas detector should be considered?
What should be paid attention to when choosing a gas detector? I believe that many people have questions, and today Shenzhen Honey Aiger Technology Co., Ltd. will answer them for you!
In some places where gas is often generated, because uncertain factors may lead to danger, it is necessary to carry out gas detection all the time, so do you know what aspects should be paid attention to when choosing a gas detector? It is necessary to pay attention to the routine calibration and detection, the main detection interference of different gases on the sensor, the life of the sensor and the concentration range of the gas detector.
How to choose the right gas detector? You need to know some necessary information, including your own needs, the working conditions of the use environment, on-site safety conditions, the functional requirements of use, and the origin of the sensor. So what should you pay attention to when choosing a gas detector?
1. Pay attention to routine calibration and testing, and use relative comparison method to measure and evaluate toxic and harmful gas detectors. First, use zero gas and standard concentration gas to calibrate the instrument to obtain a standard curve and store it in the device.
The instrument compares the electrical signal formed by the change of the target gas concentration with the concentration of the standard curve to calculate the accurate gas concentration value. Therefore, before using the gas detector and after replacing the sensor, the instrument must be calibrated to ensure that the instrument is in use. Play a protective role in the use of the instrument;
2. The main detection interference of different gases on the sensor. Generally speaking, each sensor can only correspond to a specific gas, but any gas detector cannot be absolutely special. You should try to understand the detection of other gases on the sensor interference to ensure its accurate detection of the target gas;
3. Attention should be paid to the life of the sensor. Generally speaking, the life of a portable gas detector equipped with an LEL sensor is longer, which can reach about three years, and some can reach four years or longer. The life of an electrochemical sensor for a gas is relatively long. Short, generally up to one to two years;
4. Attention should be paid to the concentration range of the gas detector. When the gas is detected, its accuracy can only be guaranteed within its measurement range. If it exceeds the measurement range for a long time, it will cause fatal damage to the sensor.
