Nitrogen Dioxide (NO₂) Gas
Nitrogen dioxide (NO₂) is a nasty-smelling gas, and is an acidic and highly corrosive gas that can affect our health and environment.
In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen dioxide.
Elevated levels of nitrogen dioxide can cause damage to the human respiratory tract and increase a person's vulnerability to, and the severity of, respiratory infections and asthma. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease. It may also affect the senses, for example, by reducing a person's ability to smell an odour. High levels of nitrogen dioxide are also harmful to vegetation damaging foliage, decreasing growth or reducing crop yields. Nitrogen dioxide can fade and discolour furnishings and fabrics, reduce visibility, and react with surfaces.

SENKO SI-100: Explosion Proof Gas Detector
SI-100 is an IEC Ex fixed gas detector installed where potential gas hazard occur to measure and monitor oxygen, toxic gas and combustible gas. Through the LCD display the SI-100 shows the concentration of gases present and the status of the unit in real time. It can be connected to a controller with a standard 4-20mA analog output communication or RS-485 digital communication. With magnetic buttons a Hot Work permit not required for calibration with no need to open the device.
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.
