Analysis on Unique Advantages of Portable Gas Detectors
We need to know that gas detection is an essential way of life, and the use of gas detectors is particularly important. With the continuous development of technology, there are many types of gas detectors, among which portable gas detectors are widely used. Next, we will analyze the unique advantages of portable gas detectors.
For portable gas detectors, they are a type of portable gas alarm characterized by small size, light weight, low power consumption, easy portability for detection anytime and anywhere. They use imported gas sensitive components, high accuracy, strong reliability, fast response and 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 based on the sampling method. For diffusion gas detectors, the gas in the detection area flows slowly and freely in the air, and the sample gas is introduced into the instrument for detection. This method is affected by the detection environment, such as ambient temperature, airflow, etc. The characteristic of diffusion gas detector is low cost. The pump suction gas detector is equipped with a small air pump, which works by driving the power supply to extract and sample the gas in the test area, and then sending the sample gas into the instrument for detection. The characteristics of a pump suction gas detector are fast detection speed, remote measurement of hazardous areas, maintenance personnel, and the same as a diffusion gas detector.
Compared to the pump suction gas detector, the working principle of the diffusion gas detector is basically the same. The sample gas is detected by the sensor of the instrument and then amplified and sorted by the circuit to convert it into corresponding numerical values for display on the screen. Catalytic combustion sensors are commonly used for combustible gases, while electrochemical sensors are commonly used for toxic gases. Both are essential security facilities for enterprise production.
