What distinguishes the gas detector's pump suction type from its diffusion type?
A gas detector is a typical gas detection tool. When employing the instrument, it is essential to employ the proper type of detection approach due to the potential existence of various elements in the detection environment. The gas detector has two operational modes: pump suction and diffusion. Let me explain the difference to you in this manner.
Pump suction gas detector and diffusion gas detector differences
1. Sampling strategy
Diffusion-type gas detectors sample by allowing air to enter the instrument freely, as opposed to pump-suction gas detectors, which typically require an air pump to sample air during sampling.
2. Detection speed: The pump-suction gas detector has a very quick detection speed, however the diffusion gas detector's detection efficiency will be slower since it will be impacted by the air flow rate during the sampling process.
3. Application scenarios: Diffusion gas detectors are typically used in open spaces, such as in open workshops, while pump-suction gas detectors are used in unique scenarios, such as tunnels, pipelines, sewers with relatively small spaces, Tanks, sealed containers, and other places where gas detection is necessary. The pump-suction gas detector can be connected with accessories for remote sampling and detection depending on the user's requirements.
