The GX-3R Gas Detector is a revolutionary advancement in gas detection technology, combining compact design, multi-gas monitoring, and advanced sensor technology in a single portable device. Weighing just 3.52 ounces and measuring 2.2″ W x 2.55″ H x 1.02″ D, it is the world’s smallest 4-gas monitor, making it easy for workers to clip within their breathing zone for accurate, real-time monitoring.
Key Benefits
Compact and Lightweight
The GX-3R’s small footprint and light weight ensure maximum comfort and mobility. Workers can wear it in their breathing zone without obstruction, allowing for precise monitoring where it matters most—around the nose and mouth.
Comprehensive Gas Monitoring
Simultaneously detects four critical gases:
- LEL combustibles
- Oxygen (O₂)
- Carbon monoxide (CO), with hydrogen-compensated CO available
- Hydrogen sulfide (H₂S)
This multi-gas monitoring provides real-time protection against multiple hazards in a single, cost-effective device.
Advanced Sensor Technology
The GX-3R features next-generation micro sensors for improved performance and durability:
- LEL sensor: Dual active filaments enhance resistance to silicone poisoning; if one filament fails, the second continues operation.
- O₂ sensor: Electrochemical design with a lifespan of 3–5 years.
- CO and H₂S combo sensor: Efficient, compact, and easy to replace.
Non-Compliance Indicator
For added safety, the GX-3R includes a non-compliance indicator:
- Flashes three LED lights every 30 seconds if calibration is due, a bump test hasn’t been performed, or a gas alarm event occurred
- Interval is adjustable and continues until the non-compliance condition is resolved
- Helps safety supervisors quickly identify compliance issues
Enhanced Worker Safety
Clipping the GX-3R within the breathing zone ensures that air samples are taken from the most relevant location, providing accurate exposure data and helping prevent overexposure to hazardous gases.
