What is the difference between pumped and diffused gas detectors?
Gas detector is a common gas detection instruments, due to the detection of different factors may exist in the environment, so the use of instruments need to use the correct type of detection method, the normal use of the state, the gas detector can be used in diffusion and pump suction two ways, the following with the difference.
Pump suction gas detector and diffusion gas detector difference
1. Sampling method:
Pump-absorption gas detector in the sampling is generally pumped through the gas pump sampling, while the diffusion gas detector sampling is free to let the air into the instrument.
2. Detection speed:
Diffusion gas detector in the sampling process will be affected by the air flow rate, so its detection efficiency will be slower than the pump suction gas detector, while the pump suction gas detector detection speed is very fast.
3. Application occasions:
Diffusion gas detector is mainly used in open occasions, such as the application of the workplace is not closed, while the pump suction gas detector is applied to the occasion is more special, such as space is relatively small pits, pipelines, sewers, tanks, sealed containers and other places need to carry out gas detection, pump suction gas detector in the use of the process of the user's use of the requirements of the external accessories to carry out long-distance sampling and detection. Sampling detection.
4. Cost of use:
The use of diffusion gas detector, whether it is the cost of manufacturing or maintenance costs, the cost of its use will be far lower than the pump suction gas detector.
