IRwin® Methane Leak Detector
Innovation that simplifies every step.
Smart Methane Detection Built for Utility Fieldwork
The IRwin portable methane leak detector provides utility crews with everything needed for faster, safer, and more accurate gas leak surveys, eliminating the need for multiple devices. Its lightweight design simplifies pipeline inspections, and advanced infrared sensing delivers quick, reliable field results. Whether scanning gas mains, addressing emergency leaks, or monitoring methane emissions, IRwin offers reliable results with minimal effort. It automatically adjusts to detect everything from the smallest gas traces to major leaks, making it a single, versatile instrument. The intrinsically safe IRwin SX model is certified for hazardous locations (Zone 0/Class I Division 1), enabling confident operation. It detects methane concentrations as low as 1 ppm, exceeding the PHMSA-specified 5 ppm threshold, aiding compliance and ensuring high accuracy.
Distinguish Swamp Gas from Real Leaks On the Spot
Avoid false alarms that waste time and cause interruptions. IRwin utilizes a built-in gas chromatograph (GC) and sensor combination to instantly determine if the gas is natural gas or swamp gas, even with ethane levels as low as 0.5%. This provides fast, confident answers without lab testing or guesswork.
ADVANTAGES AT A GLANCE
- ✔️ No false alarms
- ✔️ Improved efficiency with high sensitivity, fast response, and short recovery time
- ✔️ Accurate gas analysis through advanced IR technology
- ✔️ Fast ethane and propane detection
- ✔️ Easy distinction between natural gas and swamp gas
- ✔️ Automatic documentation of survey results
- ✔️ PHMSA compliant
TYPICAL APPLICATIONS
- Natural gas pipeline survey
- Emergency situations
- Landfill emission monitoring
- Biogas and wastewater treatment plant leak and emission monitoring
- LDAR methane emissions monitoring and quantification (Method 21)
DURABILITY YOU CAN COUNT ON
- Bright, easy-to-read screen, even in direct sunlight
- Weatherproof and robust housing (IP54-rated)
- Built for demanding field conditions
- Explosion-proof models for hazardous zones
AUTOMATIC ADJUSTMENTS FOR ACCURATE READINGS
Whether detecting a tiny leak or full gas flow, IRwin automatically adjusts using its Universal+ mode, switching between PPM, %LEL, and Vol% to provide accurate, readable results instantly. No manual toggling is required, ensuring precise data.
ACCURATE BAR HOLD READINGS IN SECONDS
The built-in CGI (Combustible Gas Indicator) function allows for accurate bar hole readings in just 15 seconds, eliminating the need for a separate device. This leads to quicker leak localization, fewer tools to manage, and less equipment to transport. By integrating multiple survey functions into one easy-to-use instrument, IRwin saves time, reduces equipment costs, and simplifies daily operations.
COMFORTABLE ENOUGH FOR LONG SHIFTS
Weighing only 1.6 kg (3.5 lb), the IRwin is designed for long survey days. Its modular probe system and quick-swap fittings allow adaptation to any environment without requiring extra gear. Crews can even change filters in the field with minimal tools.

EFFORTLESS DOCUMENTATION WITH BUILT-IN GPS AND A CHECK-IN APP
IRwin handles paperwork, allowing users to focus on the survey. The entire route is automatically tracked via built-in GPS and integrated into GIS systems for easy mapping and verification. All survey data is transferred wirelessly via Bluetooth® to a smartphone or computer, eliminating cables, manual note-taking, and data loss risks. The IRwin Check-in App enables users to create and send reports directly from the field in seconds.
PINPOINTING LEAKS WITH FEWER BAR HOLES
IRwin's powerful vacuum bell draws gas through asphalt and other paved surfaces, enabling precise leak pinpointing with fewer bar holes.
THE IRWIN INTELLIGENCE
To prevent misleading measurements or false alarms, IRwin features an infrared sensor combined with a patented gas filter. This system also prevents interference from water vapor, exhaust gases, and other VOCs.
