Reliable Ambient Air Sampling with Passive Collector Technology
Monitor agricultural air pollutants over time with AgroEnviroTest’s accurate, low-maintenance ambient air samplers.
Ambient Air Samplers
At AgroEnviroTest, our Ambient Air Samplers with Passive Collectors provide a simple yet powerful solution for monitoring atmospheric pollutants like ammonia (NH₃) and hydrogen sulfide (H₂S) over extended periods. These samplers require no power supply or active pumping systems, relying instead on natural diffusion to capture pollutants onto selective media. This low-maintenance approach is ideal for farms, composting operations, and environmental studies where baseline air quality data and odor assessments are critical. By partnering with industry leaders such as GAO Tek and GAO RFID, we offer technology that supports continuous environmental stewardship and compliance with evolving regulations across North America.
Hardware
Passive sampling tubes or badges with selective adsorbent materials are complemented by Chemical and Gas Sensorsto validate pollutant absorption data for environmental risk
Weather-resistant mounting fixtures and shelters use LoRaWAN Accessoriesto ensure secure outdoor deployment and data transmission from passive sites near financial infrastructure.
Tamper-proof, easy-to-install housings integrate UHF RFID Readers, Tags & Accessoriesto enable secure access control and audit trails at sampling locations under insurance monitoring.

Case Study
Dairy Farm Air Quality Monitoring – Wisconsin, USA
A Wisconsin dairy deployed our ambient air samplers around barns and lagoons to gather ammonia concentration data over several weeks. The data helped optimize ventilation strategies, reducing ammonia emissions by 18%.
Compost Facility Odor Assessment – Oregon, USA
An Oregon composting operation used AgroEnviroTest passive samplers to track hydrogen sulfide levels. The collected data supported community odor complaint investigations and enhanced site odor management plans.
Agricultural Air Quality Research – Manitoba, Canada
Researchers at a Manitoba university used our passive collectors for long-term monitoring of ammonia levels near grain storage facilities. The study informed best practices for minimizing emissions during storage and handling.
