|product name:||Ozone gas alarm|
|Measurement object:||Ozone in the air|
Ozone, O3, also known as superoxide, is an allotropic form of oxygen. It has poor stability at normal temperature and pressure and can be decomposed into oxygen by itself. Ozone has the smell of grass. Inhaling a small amount is beneficial to the human body. Excessive inhalation is harmful to human health. Non-flammable, pure. Oxygen can be converted into ozone by electric shock.
SK-600-O3 is an explosion-proof, fixed gas alarm with national patent license. It adopts intelligent digital electrochemical sensor monitoring technology and is widely used in agricultural production, food and beverage disinfection, chemical industry, medical care and other fields. The product uses original imported sensors: it adopts intelligent processing platform and electrochemical detection technology, which has excellent stability and strong anti-interference ability. The smallest volume in the world, fast response speed and high measurement accuracy! Infrared remote control: The alarm can be set without opening the cover, which is safe and convenient. Three-wire system 4-20mA standard current output: perfectly connected with control instrument and DCS, PLC system. Intelligent modular sensor: easy to replace and maintain, no calibration required during replacement.

① Reference concentration of ozone in the disinfection, preservation, deodorization and purification of air, space, utensils and containers (1ppm = 2.14mg / m3)
② The "Industrial Hygienic Standard" formulated by the Ministry of Health of China in 1979 stipulates that the safety standard for ozone is 0.15 ppm.
③ The concentration that causes a certain reaction of the personnel is 0.5-1ppm. The allowable contact time is 1.5 hours. If the time is long, you will feel dry mouth and other discomfort.
④ Concentrations of 1-4 ppm may cause cough in personnel. The allowable contact time is 1 hour.
⑤ Concentration of 4-10ppm will cause a strong cough. The allowable contact time is 20 minutes.
⑥ The half-life of ozone is 20-50 minutes, and the final decomposition product is oxygen, so there will be no residual pollution to food.
