Ammonia is a compound of nitrogen and hydrogen with the formula NH₃. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct characteristic of a pungent smell.
About 80% of the ammonia produced by industry is used in agriculture as fertilizer. Ammonia is also used as a refrigerant gas, for purification of water supplies, and in the manufacture of plastics, explosives, textiles, pesticides, dyes, and other chemicals.
Ammonia is not highly flammable, but containers of ammonia may explode when exposed to high heat.
It is therefore important to have suitable gas detection either Fixed or portable / Personal or both to protect workers from the effects of inhaling Ammonia (NH3)
Fixed Gas Detection
Riken Keiki GD-70D is a sample drawing intelligent gas detector that has an option of mounting several Ammonia sensors with ranges of 0-10ppm , 0-75ppm or 0-150ppm ideal for leak detection . The GD-70D can operate standalone or for large area applications can be connected to the RM-5000 Gas monitoring panel or for very large applications above 12 detection points up to 96 detection points to the GADMS Lite system for Monitoring via Smart phone , Tablet or static PC .
Personal Gas detection
The SC-04-NH3 offers cost effective single gas personal detection for Ammonia ( NH3 ) in a small compact package whereas the GX-3R Pro can combine confined space gas monitoring ( LEL / H2S / CO / O2 ) with NH3 in one small personal gas detector with Bluetooth connectivity offering email notification of gas alarms , Man down and panic alarms and GPS Location to a central point for lone worker monitoring
Portable sample draw gas monitor
GX-6000 can also mount a smart sensor for Ammonia ( NH3 ) for easy portable leak detection around pipes and containers

Plant rooms are often situated underground. This is by design to save space or by virtue of being built into existing basements or chambers. Underground Plant Rooms often contain an array of machinery such as Pumps, Boilers, Sprinkler Systems or Generators.

For more information about positioning fixed gas detectors, further guidance can be found in the new Gas Mapping Standard BS 60080 (Fire and Gas Mapping ), IEC 60079-29-2 (Explosive atmospheres – Part 29-2: Gas detectors – Selection, installation, use and maintenance of detectors for flammable gases and oxygen), and also EN 45544-4 (Workplace atmospheres – Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours. Guide for selection, installation, use and maintenance.). Additionally, The CoGDEM ( Council of Gas Detection and Enviromental Monitoring ) Guide to Gas Detection is an excellent general user guide for Gas Detection, written by those in the industry.
View StoryCatalytic combustion sensors are the standard method for detecting combustible gases including Hydrogen, however in order to operate a minimum of about 10% Oxygen needs to be present. IR sensors are a good solution to this problem for measuring most combustible gases in an inert environment where O2 levels are below 10% volume but IR sensors cannot detect Hydrogen.
Riken Keiki offers several solutions around this problem.
