Factory direct sales of industrial nitrogen dioxide NO2 detector alarm

Factory direct sales of industrial nitrogen dioxide alarm detector 15,665,820,210 nitrogen oxide NO2 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. Main features LCD concentration display, LED status indication LCD display field concentration, LED status indication field, you can display the measured running real-time. Compared to a digital signal and analog signal 4-20mA standard current signal, before exchange without first commissioning, they can always freely exchange gas detector position, easier to maintain. Advantages of high accuracy, transmission distance, interference well. Measurement accuracy sensor using imported gas sensors, high precision, zero drift, anti-toxic properties. Explosion-proof design for hazardous plant conditions 1,2 occasion. Easy maintenance sensor modules using digital design, without zero when a field replacement, calibration. Certification Tianjin: Exd II C T6 Gb Ministry of Public Security: Fire Product Conformity Assessment Center application standards: GB15322.1-2003, GB12358-2006 Environmental IP rating: IP65 Operating temperature: -40 ℃ ~ 70 ℃ Humidity range: 10% RH ~ 95 % RH Pressure range: 86Kpa ~ 106Kpa Storage temperature: -25 ℃ ~ 55 ℃ care of the security of every worker.
