What kinds of portable gas detectors are there?
Portable gas detector is a common instrument in the field of gas detection in industrial environments. It has the function of accurate measurement, but because of its different types, it can be used in a variety of environments.
Types of Portable Gas Detectors
1. The pump-suction portable gas detector uses a small air pump when it involves, and its working method is that the power supply drives the air pump to pump and sample the gas in the area to be detected, and then send the sampled gas into the instrument for detection. The main feature of the pump-suction portable gas detector during use is its fast detection speed. It can perform long-distance measurement when used in a dangerous area, which can ensure the safety of the staff to a certain extent. The rest of the features are similar to those of the diffused portable gas detector. The detectors are basically the same.
2. When the diffusion type portable gas detector is used, the gas in the detection area is slowly sent into the instrument for detection under the condition of free air flow. However, the user will be affected by the detection environment to a certain extent when using this method, such as ambient temperature, airflow and other factors will affect it. The main feature of diffusion portable gas detectors is low cost.
The types of portable gas detectors are mainly divided into pump-suction gas detectors and diffusion gas detectors. Both instruments have their own characteristics when in use, so when users choose the type of instrument, they can choose according to their own requirements. Appropriate equipment for your own use.
