Original source: Meet the sulfur dioxide detector to admit defeat. Edit: Lin frequency instrument
The role of the sulphur dioxide detector is simply to measure the concentration of sulphur dioxide in the air. The outer casing is made of high-strength engineering materials and composite elastic rubber materials. It has the advantages of high strength, good hand feeling, waterproof, dustproof and explosion-proof. There are two types of sulfur dioxide detectors. Now I will explain it to you by Lin Pinxiao.
Portable sulfur dioxide detector:
It is a safety device that can continuously detect the concentration of toxic and harmful, flammable and explosive gases in the environment. It is used for explosion-proof, toxic gas leakage, underground pipelines or mines, etc., which can effectively guarantee the safety of workers' lives. The sulfur dioxide detector uses a natural diffusion method to detect the gas concentration. The imported electrochemical sensor (combustible gas is used as the catalytic combustion type) has the characteristics of simple operation, complete functions, high reliability, good sensitivity and repeatability.
Single point wall mounted sulfur dioxide detection:
For the natural diffusion method to detect the gas concentration, the imported electrochemical sensor or the catalytic combustion sensor is used, which has the characteristics of good sensitivity and repeatability; the liquid crystal screen displays the concentration value of the leaking gas, and exceeds the preset alarm point. Immediately start the sound and light alarm signal or drive the exhaust system; the international standard 4-20mA signal can be connected to the factory's DCS system, equipped with RS485 communication interface.
