The difference between pump type and diffusion type gas detector:
The main difference between pump and diffusion gas detectors is their sampling method and application. The following is a detailed introduction:
Sampling method. The pump type gas detector actively extracts the gas in the air through the built-in suction pump for detection, while the diffused gas detector relies on the natural flow of air into the detector for detection. Where applicable. The diffused gas detector is usually used in open situations, such as open work workshops, while the pumped gas detector is suitable for special occasions, such as confined Spaces, tunnels, pipelines, sewers, tanks and other places that need to be tested. Detect the speed. The detection speed of pump gas detectors is usually faster than that of diffusion gas detectors, because they can more quickly suck the gas to be measured into the instrument for detection Cost. Pump suction gas detectors typically cost more than diffused gas detectors because they require a built-in suction pump and other electronic components. In addition, the pumped gas detector can be remotely sampled by external accessories, while the diffused gas detector is more susceptible to environmental factors such as wind speed and temperature.
