product description

Product introduction:

Harmfulness of gas: It has irritation and anesthesia effect on eyes and upper respiratory tract mucosa. Acute poisoning: at high concentrations, it immediately causes eye and upper respiratory tract irritation, causing eye pain, tearing, runny nose, sneezing, sore throat, cough, etc., followed by headache, dizziness, nausea, vomiting, general weakness, etc .; severe cases May have dizziness and gait. Burns can occur when the eyes are contaminated with styrene liquid. Chronic effects: common neurasthenia syndrome, including headache, fatigue, nausea, loss of appetite, bloating, depression, forgetfulness, finger tremor, etc. It has a stimulating effect on the respiratory tract, and long-term exposure sometimes causes obstructive pulmonary disease. Rough, chapped and thickened skin. Styrene is a flammable and explosive gas, a suspected carcinogen, and irritating.

The styrene gas alarm consists of an alarm controller and a gas detector. The controller can be placed in the duty room and mainly controls the monitoring points. The gas detector is installed at the place where the gas is most likely to leak. The core of the gas detector The component is a built-in gas sensor, which detects the concentration of gas in the air. The gas detector converts the body concentration detected by the sensor into an electrical signal and transmits it to the controller through the cable. The higher the gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the gas concentration The alarm sends out an alarm signal and can activate externally connected equipment such as solenoid valves, exhaust fans, and automatically eliminate hidden dangers.
