Analysing the unique benefits offered by portable detectors
We must know that gas detection is an essential method in life, and the use of gas detectors is very important. With the continuous development of science and technology, there are many types of gas detectors, among which portable gas detectors are widely used. Next, the unique advantages of portable gas detectors will be analyzed.
The portable gas detector is a portable gas alarm. Its main features are small size, light weight, low power consumption, easy to carry and can be detected anytime and anywhere. It uses imported gas sensitive components with high precision, strong reliability and responsiveness. It has fast recovery time, good gas selectivity and strong anti-interference ability. Portable gas detectors can be divided into diffusion gas detectors and pump-type gas detectors according to the sampling method. Among them, for diffusion gas detectors, the gas in the detection area flows freely in the air and slowly flows the sample gas into the instrument for detection. This method is affected by the detection environment, such as ambient temperature, air flow, etc. Diffusion gas detectors are characterized by low cost. The pump-type gas detector is an instrument equipped with a small air pump. Its working method is that the power supply drives the air pump to pump and sample the gas in the area to be measured, and then the sample gas is sent to the instrument for detection. The pump-type gas detector is characterized by fast detection speed, long-distance measurement in dangerous areas, and maintenance of personnel safety. Others are the same as diffusion-type gas detectors.
Compared with the pump-type gas detector, the working principle of the diffusion-type gas detector is basically the same. The sample gas is detected by the sensor of the instrument and then amplified and converted by the circuit into the corresponding value and displayed on the screen. Catalytic combustion sensors are commonly used for combustible gases, and electrochemical sensors are commonly used for toxic gases. Both are indispensable security facilities for enterprise safety production.
As a kind of security facility, portable gas detectors play an important role in industrial production safety. In order to ensure the normal use of the gas detector, we need to test the gas detector before use. When testing the portable gas detector Here are a few aspects to focus on:
First: Start up in a non-hazardous area under normal environmental conditions.
Second: Do not replace or charge the battery in hazardous areas. Doing so will compromise the safety of the instrument and may result in fire or explosion.
Third: Do not use a butane lighter to light a cigarette to test the response of the combustible gas sensor; doing so will damage the sensor.
Fourth: Do not immerse the gas detector in liquid.
Fifth: When the gas detector issues a low-power alarm, replace the battery immediately (check the instruction manual for battery type).
Sixth: Protect combustible gas sensors from exposure to lead mixtures, silicones, and chlorine-containing hydrocarbons.
The portable gas detector is a hand-held gas detector that is small in size and easy to carry and can detect gas leakage concentration anytime and anywhere. It has the characteristics of high sensitivity, stable operation, fast response and recovery time, good gas selectivity, and strong anti-interference ability. It uses high-performance lithium batteries and has a long working time. It also adopts charging protection and low-voltage protection to ensure more reliable battery use. Longer life.
