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.

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.
Locally Technically Supported by Gas Detection Australia
GDA 2000Tx Explosion Proof (IEC Ex) Toxic and Oxygen Gas Detector is certified for use in Zone 1 Hazardous areas within Australia.
Locally Technically Supported by Gas Detection Australia
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. Utilising magnetic switchs so that Hot Work permit not required for calibration.
Locally Technically Supported by Gas Detection Australia
Designed to be used where areas that are difficult to gain access due to distance or toxic environment. As well as to detect greater ranges of toxic gases using advanced Pyrolyzer technology converting electrochemically inactive gases to easily detected gases.
