Nitrogen Dioxide (NO₂) Gas
Nitrogen dioxide (NO₂) at higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant. For the general public, the most prominent sources of NO₂ are internal combustion engines burning fossil fuels. Outdoors, NO₂ can be a result of traffic from motor vehicles. Indoors, exposure arises from cigarette smoke, and butane and kerosene heaters and stoves.
Workers in industries where NO₂ is used are also exposed and are at risk for occupational lung diseases. Astronauts in the Apollo–Soyuz Test Project were almost killed when NO₂ was accidentally vented into the cabin. Agricultural workers can be exposed to NO₂ arising from grain decomposing in silos; chronic exposure can lead to lung damage in a condition called "Silo-filler's disease".

SENKO SI-100: Explosion Proof Gas Detector
SI-100 is a IEC Ex fixed gas detector installed in a place where potential gas hazard occurs to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LCD display and can be connected to the controller with a standard 4-20mA analog output communication or RS-485 digital communication.
SENKO SI-100C: Explosion Proof Gas Sensor
SI-100C is a IEC Ex explosion proof gas sensor ready to installed hazardous and non-hazardous areas to prevent gas hazards caused oxygen depletion, toxic gas or combustible gas. Available to detect over 25 different gas types, see Ordering Information for details.
SENKO SGT: Disposable Portable Single Gas Detector
The SENKO SGT is a low cost disposable sensor, guaranteed 2 years operating life without recharging or calibration required.
