High-Precision Ammonia (NH₃) Sensors for Critical Monitoring
Detect and track ammonia concentrations with advanced sensor systems tailored for industrial, agricultural, and environmental use cases.

Ammonia Gas Detection Solutions for Harsh Environments
Ammonia (NH₃) is a pungent, toxic gas commonly found in agricultural operations, industrial manufacturing, wastewater facilities, and refrigeration systems. Exposure to elevated levels can pose severe risks to human health and the environment. Continuous and accurate NH₃ monitoring is essential to safeguard workers, meet regulatory standards, and optimize operational safety.
Modern ammonia sensors deliver reliable real-time detection and data analytics across a range of harsh and dynamic environments. For B2B companies operating in sectors such as agriculture, energy, food processing, and municipal water treatment, integrated NH₃ sensing solutions are vital for emissions control, leak detection, and air quality management.
Air Quality Instruments serves clients across North America with state-of-the-art NH₃ sensor systems built for accuracy, scalability, and durability. Through our collaborative partnerships, industry insight, and customer-focused approach, we help businesses adopt advanced, intelligent air quality technologies tailored to their specific needs.

Case Studies
Dairy Farm Monitoring, Wisconsin
A large-scale dairy farm in Wisconsin implemented Air Quality Instruments’ electrochemical NH₃ sensors to monitor ammonia buildup in enclosed barns. The system provided real-time ventilation control data and alert systems, which led to a 42% improvement in indoor air quality and significantly reduced animal health incidents and worker complaints.
Industrial Refrigeration, Texas
An ammonia-based refrigeration facility in Texas deployed fixed-point TDLAS ammonia sensors across critical equipment zones. The early detection system identified micro-leaks, helping the team prevent major shutdowns. Within three months, the company recorded a 60% reduction in unplanned maintenance.
Wastewater Treatment, Ontario
A municipal wastewater treatment plant in Ontario integrated multi-gas sensor nodes to monitor ammonia in processing and discharge areas. Data collected via cloud services allowed for regulatory reporting under CEPA and optimized aeration system performance, lowering operational energy costs by 15%.
