The fixed NO2 gas detector can continuously detect nitrogen dioxide concentration online in some harsh environments. NO2 sensor can not only control the concentration of nitrogen dioxide gas in special occasions, but also have an early warning effect on the leakage of nitrogen dioxide gas in dangerous sites. Fixed NO2 gas detector is widely used in petroleum, chemical, metallurgy, fire, coal mine, electric power, shipping, environmental protection and other industries. It has the advantages of stable signal, high precision and good repeatability. Nitrogen dioxide sensor output a variety of standard signals, can be compatible with a variety of alarm systems, PLC, DCS and other control systems.

1, the fixed NO2 gas sensor is small in size and light in weight. When it is started or needed to use, it is necessary to self-check the display, battery, sensor, sound and light, vibration alarm function.
2, the use of non-slip, waterproof and integrated design, maintenance cost is very low.
3. The patented sensing and detection technology provides temperature compensation and impact protection
4, single button on/off, can intuitively prompt characters suitable for a variety of languages, regular flashing light/sound prompt.
5, has the “reverse” display function, more than the harsh electromagnetic protection requirements.
