Ammonia (NH3) Detectors

We provide a comprehensive range of fixed and portable ammonia gas detectors to suit different operational needs. Fixed systems deliver continuous monitoring for large areas or process facilities, while portable units offer dependable personal protection in environments where exposure levels may fluctuate.

Our range includes trusted solutions from BW, Dräger, Crowcon, GMI, MSA, Riken Keiki, RAE Systems, Senko, and Uniphos. These detectors feature advanced sensor technology, robust designs, and user-friendly operation — ensuring reliable performance in demanding environments.

Safeguard your workforce and ensure safe operations with our range of fixed and portable ammonia detection systems. Portable detectors are also available for hire.

Our detectors utilise electrochemical sensors for accurate measurement of ammonia concentrations across workplace exposure ranges. With fast response times, robust construction, and straightforward calibration, these instruments provide confidence in demanding industrial conditions.

Ammonia (NH₃) is widely used in industries including refrigeration, agriculture, and food processing. While essential in these environments, ammonia vapour is corrosive and can cause immediate irritation to the eyes, skin, and respiratory tract. Prolonged or high-level exposure may lead to severe health complications, making reliable monitoring vital to maintaining safe operations and protecting personnel.
