Examination of the Special Benefits of Portable Gas Detectors
We need to know that gas detection is a necessary way 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, and then the unique advantages of portable gas detectors are analyzed.
The portable gas detector is a kind of portable gas alarm. Its main features are small size, light weight, low power consumption, easy to carry and can detect anytime and anywhere. It adopts imported gas sensitive components, high precision, strong reliability, and responsive Fast recovery time, good gas selectivity, and strong anti-interference ability. Portable gas detectors can be divided into diffusion gas detectors and pump suction gas detectors according to the sampling method. Among them, for the diffusion gas detector, 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, airflow, etc. Diffusion gas detectors are characterized by low cost. The pump-suction gas detector is equipped with a small air pump. Its working method is that the power supply drives the air pump to extract and sample the gas in the area to be measured, and then send the sample gas into the instrument for detection. The pump-suction gas detector is characterized by fast detection speed, long-distance measurement of dangerous areas, and maintenance of personnel safety. Others are the same as diffusion gas detectors.
Compared with the pump-suction gas detector, the working principle of the diffusion gas detector is basically the same. The sensor of the instrument detects the sample gas and then amplifies it through the circuit and converts it into a corresponding value and displays it on the screen. Catalytic combustion sensors are commonly used for flammable gases, and electrochemical sensors are commonly used for toxic gases. Both are indispensable security facilities for safe production of enterprises.
As a security facility, portable gas detectors play an important role in industrial production safety work. In order to ensure the normal use of gas detectors, we need to test the gas detectors before use. When testing the portable gas detectors Here are a few things to focus on:
First: Start the machine under normal environmental conditions in a non-hazardous area.
Second: Do not replace or recharge batteries in hazardous areas. Doing so will impair the safety of the instrument itself 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 manual for the battery type).
Sixth: Protect combustible gas sensors from exposure to lead mixtures, silicon and chlorinated hydrocarbons.
For the portable gas detector, it is a hand-held gas detector that is small in size, easy to carry and can detect the concentration of gas leakage 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 adopts high-performance lithium battery and has a long working time. At the same time, it adopts charging protection and low-voltage protection to ensure that the battery is more reliable. Longer life.
