Protect Your Team
& Operations with
Continuous, Low-PPM
Methyl Bromide Monitoring
- EPA-Approved Real-Time Detection
- Sub-TLV Accuracy (0.5 ppm)
- Lowest Annual Maintenance Costs
Transition to Continuous Protection
The Risk
Methyl bromide leaks in fumigation chambers, fruit storage, and commodity facilities pose serious health risks. Manual tubes are labor-intensive, provide only snapshots in time, and are notoriously unreliable for continuous safety monitoring.
PureAire Solution
Compact extractive system with built-in pump (samples up to 300 ft away), pyrolyzer + renewable electrochemical sensor for stable, accurate sub-TLV measurements. Providing reliable, continuous methyl bromide safety monitoring.
The Only Monitor Explicitly Recognized by California EPA/DPR
PureAire Monitoring’s Air Check Advantage is recognized by the California Department of Pesticide Regulation (DPR) as an equivalent—or better—alternative to traditional colorimetric tubes for monitoring enclosed fumigation areas, commodity storage, and treatment facilities.
Continuous remote monitoring allows personnel to measure methyl bromide levels without entering hazardous areas, improving worker safety and supporting regulatory compliance.
- EPA/DPR Recognized Technology
- Continuous Remote Monitoring
- Real-Time Low-PPM Detection
- Reduced Worker Exposure
Key Features & Benefits
Built for continuous low-ppm detection with reliable performance, simple maintenance, and easy integration into industrial monitoring systems.

How PureAire Detects Methyl Bromide
How It Works
Install
Mount the unit outside hazard zones and run tubing up to 100 ft into sampling area.
Monitor
Electrochemical sensor monitors methyl bromide levels continuously at Sub-TLV resolution.
Alert
Dual built-in alarm relays trigger strobe lights or sirens immediately upon leak.
Report
Output 4-20mA telemetry back to your master PLC/SCADA for seamless compliance logging.
Cost Savings & ROI

Why Choose PureAire Over Fixed Alternatives?
Versus Competitor: PureAire for safety-focused low-ppm continuous monitoring in storage (EPA-backed); Competitor stronger for high-range multi-zone fumigation dosing with web portal.
Versus Generic Fixed/PID: Superior specificity, lower cross-sensitivity, proven regulatory approval, and dramatically lower TCO.
PureAire: Engineered/assembled/tested in Illinois since 1997. Financially stable stocking manufacturer with live customer support.
Where PureAire Protects
Our monitoring systems protect workers and facilities across industries where toxic gas exposure is a critical concern.
Fruit storage & commodity
facilities
Continuous gas monitoring ensures safe storage conditions and protects against harmful exposure in large-scale fruit and commodity warehouses.
Fumigation chambers
& control rooms
Real-time detection of fumigant gases keeps operators safe and ensures compliance with regulatory thresholds inside enclosed treatment zones.
Industrial gas handling
& scrubber systems
Advanced sensor arrays monitor scrubber efficiency and detect leaks across complex industrial gas handling infrastructure in real time.
