Analysis of the unique benefits of portable gas detectors
We need to know for gas detection is a necessary way of life, at the same time for the use of gas detectors is very important. With the continuous development of science and technology, there are many types of gas detectors, including portable gas detectors are widely used, the next for the unique advantages of portable gas detector analysis.
For portable gas detector is a portable gas alarm, its main feature is small size, light weight, low power consumption, easy to carry can be detected at any time and place, the use of imported gas-sensitive components, high precision, high reliability, fast response and recovery time, good gas selectivity, strong anti-interference ability. Portable gas detector according to the sampling method can be divided into diffusion gas detector and pump suction gas detector. Which for the diffusion gas detector is the detection area of the gas in the air free flow slowly the sample gas into the instrument for detection. This way is affected by the detection environment, such as ambient temperature, airflow and so on. Diffusion gas detector is characterized by low cost. Pump suction gas detector is equipped with a small gas pump, the way it works is the power supply to drive the gas pump to be tested in the region of the gas pumping sampling, and then the sample gas into the instrument for testing. Pump-absorption gas detector is characterized by fast detection speed, now on the dangerous areas can be measured at a distance, to maintain personnel safety, other and diffusion gas detector.
Relative to the pump suction gas detector, and diffusion gas detector works basically the same principle, through the instrument's sensors on the sample gas detection and then through the circuit to amplify and organize the conversion into the corresponding value displayed on the screen. Combustible gases commonly used catalytic combustion type sensor, toxic gases commonly used electrochemical type sensor. Both are indispensable security facilities for enterprise safety.
Portable gas detector as a security facility in industrial production ** work plays an important role, in order to ensure the normal use of the gas detector we need to test the gas detector before use, in the portable gas detector to test the main aspects of the following: in non-hazardous areas, normal environmental conditions under power. Safety: Do not replace or charge the battery in hazardous areas. Doing so will jeopardize the safety of the instrument itself and may result in fire or explosion. Third: Do not use a cigarette butane lighter to test the response of the gas sensor; doing so will damage the sensor. Fourth: Do not immerse the gas detector in liquid. Fifth: Replace the batteries immediately when the gas detector gives a low power alarm (check the manual for battery type). Sixth: Protect the gas sensor from exposure to lead mixtures, silicones and chlorinated hydrocarbons.
For portable gas detector is a small size, easy to carry can be anytime and anywhere for the detection of gas leakage concentration of hand-held gas detector. With high sensitivity, stable operation, fast response and recovery time, good gas selectivity, strong anti-interference ability, etc., the use of high-performance lithium batteries, long working time, while the use of charging protection and low-voltage protection, to ensure that the battery use more reliable, longer life.
