Mianyang nitrogen dioxide leak alarm

Zhenjiang, Jiangsu NO2 nitrogen dioxide alarm detector 15,665,820,210 nitrogen oxide poisoning mostly oxide and nitrogen dioxide (NO2) due. Nitrogen dioxide is a reddish-brown gas, insoluble in water, with a characteristic sweetness. Nitrogen oxides in many occupations can be exposed to, including the use of acetylene torch welding, electroplating, metal cleaning and mining industries, as well as contact with nitrogen oxides are likely in the manufacture of dyes, paints or nitric acid process. Contacts 150mg / m3 of nitrogen dioxide than 3 ~ 24h after respiratory symptoms such as cough, fever, shortness of breath and other blood stained sputum, extreme weakness, nausea and headache.
