Ammonia (NH3) Detection

Portable & fixed-point NH3 detectors for healthcare, pharmaceuticals, chemical manufacturing, agriculture, and environmental testing.

About Ammonia Detection

A colorless gas with a distinctive sharp smell, Ammonia is a cornerstone in numerous industries such as agriculture, pharmaceuticals, refrigeration, and manufacturing.

Its widespread use is evident in fertilizer production, waste and wastewater treatment, and the creation of explosives. In the realm of manufacturing, ammonia plays a pivotal role in the production of plastics, fibers, and other chemicals. Though invaluable, ammonia’s toxicity is a significant hazard, particularly in enclosed industrial environments, requiring stringent detection protocols to ensure worker safety. Prolonged exposure even at low levels can have adverse health effects, making its management in the workplace critical.

Common Challenges

  • Difficulty in detecting low concentrations of ammonia, which can still pose health risks.
  • Ensuring reliable and continuous monitoring in harsh industrial environments.
  • Mitigating false alarms due to the presence of other chemicals and environmental factors.


  • OSHA Permissible Exposure Limit (PEL): 50 parts per million (ppm) over an 8-hour workday.
  • NIOSH Recommended Exposure Limit (REL): 25 ppm over a 10-hour workday.
  • NIOSH Short-Term Exposure Limit (STEL): 35 ppm over 15 minutes.


Ammonia is a fundamental ingredient in fertilizer production, providing the essential nitrogen that plants require to grow. In agriculture, ammonia-based fertilizers are applied to crops to enhance yield. However, ammonia's volatility means it can escape into the air, necessitating the monitoring of NH3 levels to minimize environmental impact and ensure worker safety Read more...
