What matters need attention in the process of purchasing gas detectors
I believe everyone knows that a gas detector is an instrumentation tool for gas leakage concentration detection. Its function is mainly to use gas sensors to detect the types of gases that exist in the environment, whether they exceed the standard, etc. In order to buy a good gas detector, we must pay attention to its details. So what details should be paid attention to when purchasing a gas detector?
1. If there are more organic toxic and harmful gases, considering the low concentration that may cause personnel poisoning, you can choose a four-in-one gas detector and a VOC detector instead of using an ordinary detector, because this may cause Casualties. If the gas types cover the above types of gases, choosing a composite gas detector may achieve twice the result with half the effort.
2. Confirm the type and concentration range of the gas to be detected: the types of gases encountered by each production department are different. When choosing a gas detector, all possible situations must be considered.
3. If there are mostly methane and other less toxic alkanes, it is undoubtedly the most appropriate to choose the corresponding detector. This is not only because of the simple principle and wide application, but also has the characteristics of convenient maintenance and calibration.
4. If there are toxic gases such as carbon monoxide and hydrogen sulfide, it is necessary to choose a specific gas detector first to ensure the safety of workers.
How long is the gas detector life?
1. Most of the sensors used to measure the concentration of toxic gases are electrochemical sensors. It is a sensor based on electrochemical principles. The main factor affecting its life is the electrolyte. After 2-3 years in an ideal environment, the electrolyte of a general sensor will It can no longer work normally if it is consumed, so the service life of the electrochemical sensor is 2-3 years.
2. Most of the sensors used to detect the concentration of combustible gases are catalytic combustion sensors, and their service life is 3-5 years under ideal conditions. In addition, the life of the gas detector (including fixed gas alarm and portable gas alarm) sensor has a great relationship with the concentration it is exposed to.
Therefore, the main factor affecting the life of the sensor is that the worse the environment it is in, the shorter the life, followed by the mechanism of the sensor. Sensors directly affect the use of gas detectors, so paying attention to the use and status of sensors means paying attention to our own safety.
