Compact Safety – 4-Gas Detection for Confined Spaces & Industrial Sites
The RKI Instruments GX-3R Gas Detector Bundle is the smallest and lightest 4-gas monitor available, designed for professionals working in confined spaces, hazardous environments, and industrial settings. This bundle includes the GX-3R detector (LEL, O₂, H₂S, CO), a rechargeable Li-Ion battery, 100–240 VAC charger, and the RP-3R motorized pump with a 20ft hose and 10-inch probe—giving you everything you need for reliable, portable gas detection.
Key Features
- Simultaneous Detection: Monitors LEL, Oxygen (O₂), Hydrogen Sulfide (H₂S), and Carbon Monoxide (CO).
- H₂ Compensated CO Sensor: Reduces false readings in hydrogen-rich environments.
- Simple Operation: Two-button interface for easy use in the field.
- Triple Alarm System: Audible (100 dB), visual (LEDs), and vibration alerts.
- User-Adjustable Alarms: Customize up to 3 alarm levels per gas.
- Long Battery Life: Up to 25 hours of operation on a full charge.
- Durable Design: IP66/68 rated for water and dust resistance.
- RP-3R Pump: Clip-on motorized pump with 20ft hose and 10-inch probe for remote sampling.
Why It Works for You
This bundle empowers safety teams and field workers to detect life-threatening gases quickly and accurately. Its compact size means it won’t weigh you down, while the RP-3R pump allows remote sampling in confined or hard-to-reach areas. Whether you’re inspecting tanks, tunnels, or industrial zones, this tool helps you breathe easy—literally.
