The full name of PID in English is Photo Ionization Detectors, that is, optical ionization detection. The principle is to photoionize various types of gases to be measured by ultraviolet light emitted by an ultraviolet lamp. After the gas is ionized, it will be split into positive ions and negative ions. The positive ions will rush to the negative plate, and the negative ions will rush to the positive plate.. Generating a weak charge during the collision. The weak charge is converted into a weak current...--gas detector PID
And then amplified by the detector circuit board to obtain display data. Later, when these positive and negative ions leave the area of the positive and negative plates, they will recombine. Therefore, PID is also considered a non-destructive detection principle....It should be noted that not all gases can be detected with PID gas detectors. This is mainly related to the ionization potential of the ultraviolet lamp in the sensor... That is, the gas higher than the ionization potential cannot be separated by ionization
The PID photoionization probe& pid sensor realizes rapid detection of VOC gas, is waterproof..Easy to clean, durable, multi-range selection, and accurate measurement. PID module is high sensitive and quick react. It can help you alarm the VOC at the first time and make sure your health，gas detector PID
gas detector PID Features:
When entering VOC gas environment.... The response speed is less than 3 seconds and the speed of returning to zero is very fast.... It can help you detect VOC immediatly;
(2) Waterproof and breathable membrane
High protection, easy to clean, waterproof breathable membrane effectively protect from particles and water vapor; easy to clean and repair;
(3) Small size, light weight
Small size, easy to install, can be carried in portable, fixed pipe and other appearance sensors.
gas detector PID Application:
Pid sensor (PID optical ion probe) is widely used in VOC detection in factories. mining areas....Chemical industry areas and other environments.
