Anhydrous Ammonia



AirQuality Limited can offer three options for the monitoring of ammonia including:

-Electrochemical monitoring
-Optical sensor technology
-Canister sampling

More detail on each of these options is shown below:

Electrochemical Monitoring

These instruments use electrochemical sensors to detect ammonia and are ideally suited to industrial applications. Our monitors are configured to send the information to either a secure on-line database where the data and diagnostic information can be displayed or the clients own database for in-house reporting purposes.

Optical Sensor Technology

The optical sensor is very sensitive down to 1ppm and very selective and does not suffer from the cross sensitivity that affects most electrochemical sensors. The path length can be varied from a few centimeters to tens or metres to suit a clients needs. The results from the analyser are transmitted to a secure website where the data can be displayed and viewed online.

The monitor can be configured to The results can be displayed.


Pricing is dependent upon:

  • The length of time you wish to monitor for
  • The type of equipment you wish to use
  • Whether you wish to purchase or rent the monitoring instrumentation
  • The level of data validation and reporting
  • Whether an instrument enclosure is required
  • Whether mains or solar powered options are required
  • Whether meteorological monitoring is also required

Our clients tell us that we offer very competitive quotes for both the supply and operation of these instruments.

Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers.

Although in wide use, ammonia is both caustic and hazardous. The global industrial production of ammonia for 2012 is anticipated to be 198 million tonnes, a 35% increase over the estimated 2006 global output of 146.5 million tonnes.

Ammonia is irritating and corrosive. Exposure to high concentrations of ammonia in air causes immediate burning of the nose, throat and respiratory tract. This can cause bronchiolar and alveolar edema, and airway destruction resulting in respiratory distress or failure.

Inhalation of lower concentrations can cause coughing, and nose and throat irritation. Ammonia’s odor provides adequate early warning of its presence, but ammonia also causes olfactory fatigue or adaptation, reducing awareness of one’s prolonged exposure at low concentrations.

Children exposed to the same concentrations of ammonia vapor as adults may receive a larger dose because they have greater lung surface area-to-body weight ratios and increased minute volumes-to-weight ratios. In addition, they may be exposed to higher concentrations than adults in the same location because of their shorter height and the higher concentrations of ammonia vapor initially found near the ground.
