Ammonia (NH₃) Gas
Ammonia is a compound of nitrogen and hydrogen with the formula NH₃. The simplest pnictogen hydride, ammonia, is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Ammonia is named for the Ammonians, worshipers of the Egyptian god Amun, who used ammonium chloride in their rituals.

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.
