Portable PID photoionization detector for VOC testing

Description :

　　The VOC detector can detect the following gases:

　　Including: benzene, ethylene, styrene, vinyl chloride, nitric oxide, nitrogen dioxide, dichloroethylene, trichloroethylene, tetrachloroethylene, tetrachloroethylene, acetylene, carbon disulfide, methanol, ethanol, phosphine, acetone, gasoline, petroleum gas, bromomethane, ammonia, dichloromethane, ammonia, and other gases.

　　The use of VOC detectors in confined spaces:

　　When using VOC detectors in confined spaces, attention should be paid to flammable and harmful gases, such as reaction tanks, sewers, ship cargo holds, underground facilities, and other environmental environments. Before entering a sealed environment, testing must be conducted. In this situation, it is necessary to choose a detector with a suction pump, because in a closed environment, due to the lack of air circulation, gas diffusion is slow, and the gas distribution in different parts varies greatly. For example, combustible gases have a lighter mass;

　　Most of them are distributed in the upper layer of enclosed spaces, where carbon monoxide has a mass similar to air and is generally located in the middle layer of the enclosed space. Heavier gases such as hydrogen sulfide are located at the bottom of the enclosed space. In addition, considering the hazardous gases in enclosed spaces, a built-in suction pump should be used for non-contact long-distance detection of multiple gases. At the same time, it is easy to carry and does not affect workers' work, so as to ensure the safety of personnel entering enclosed spaces;

　　In addition, after entering a sealed environment, it is necessary to continuously detect the internal gas to prevent leakage and changes in hazardous gas concentration caused by temperature and other factors.

　　The VOC detector is a portable, high-precision, intrinsic safety device with a built-in micro sampling pump; The instrument adopts sensor and microcontroller technology from imported global sensor manufacturers, with fast response speed, high measurement accuracy, good stability and repeatability, and various parameters that can be customized by users for easy operation; LCD dot matrix display technology supports graphic and textual descriptions, with a switchable interface between Chinese and English.

　　The use of VOC detectors in open spaces:

　　In an open workshop, a portable VOC detector is used to display the VOC concentration on site at any time, anywhere. Some portable VOC detectors are also equipped with vibration alarm accessories to prevent the alarm sound from being inaudible in the presence of noise.
