What is the difference between the pump suction type and the diffusion type in the gas detector
Gas detector is a common gas detection instrument. Due to the possible existence of different factors in the detection environment, it is necessary to use the correct type of detection method when using the instrument. In normal use, the gas detector can use both diffusion and pump suction. In this way, let me introduce the difference to you.
Difference between pump suction gas detector and diffusion gas detector
1. Sampling method:
Pump-suction gas detectors generally use an air pump to sample air during sampling, while diffusion-type gas detectors sample by freely allowing air to enter the instrument.
2. Detection speed:
The diffusion gas detector will be affected by the air flow rate during the sampling process, so its detection efficiency will be slower than that of the pump-suction gas detector, while the detection speed of the pump-suction gas detector is very fast.
3. Application occasions:
The main application fields of diffusion gas detectors are in open places, such as in unclosed workshops, while pump-suction gas detectors are used in special occasions, such as tunnels, pipelines, sewers with relatively small spaces, Tanks, sealed containers and other places where gas detection is required, the pump-suction gas detector can be connected with accessories for remote sampling and detection according to the user's requirements during use.
4. Use cost:
When using a diffusion gas detector, whether it is the manufacturing cost or the later maintenance cost, its use cost will be much lower than that of the pump-suction gas detector.
