RKI Instruments GX-3R Four-Gas Detectors
RKI Instruments GX-3R Four-Gas Detectors
• Simple 2-button operation
• 25-hour battery life
• IP66/68-rated for superior water protection
At only 3.52 ounces, the GX-3R gas detector is the smallest and lightest four-gas detector available. It’s great for detecting dangerous gases in the ten inch radius around your nose and mouth, designated by OSHA as the breathing zone. Just clip it to your collar or lapel to monitor LEL combustibles, O₂, CO and H₂S.
Built for rigorous conditions, the GX-3R gas detector features an impact-resistant IP66/68-rated case with removable rubber boot that withstands drop tests over 20 feet. Simple two-button operation makes it very user friendly. Long-lasting sensors and sensor filters are field-replaceable.
The backlit LCD shows real-time gas concentrations along with intuitive health check, sensor and battery-life icons. A triple alarm system activates beeping, flashing and vibrating alarms in the event of low, high, TWA, STEL or O₂ conditions. To prevent noncompliance, three LEDs flash every 30 seconds to alert you when bump testing or calibration are overdue, or when a gas alarm event has occurred. The lights continue to flash until noncompliance conditions have been resolved.
The GXR-3R detector logs user ID, station ID, calibration and bump test history, alarm events, and alarm interval trends. Use the IR communications port to transfer logged data to a Windows-based PC for analysis and reporting (requires Data Logger Management software; available free at rkiinstruments.com). For automated calibration and logging capabilities, use the optional SDM-3R docking station (sold separately below).
Includes: alligator clip, protective rubber boot, charger and calibration adapter. 3-year warranty (instrument and sensors).

SDM-3R Docking Stations
SDM-3R Docking Stations
Automate calibration, bump testing and datalogging with the SDM-3R docking station. When used as a stand-alone unit, it stores 200 calibrations, 214 bump tests or 469 alarm checks for future upload to your PC via the included USB flash drive and free SDM Docking Station software (download from rkiinstruments.com).
When directly connected to your PC, the docking station lets you manage up to 10 gas detectors at once. Set up automatic calibration, bump testing, alarm checks, charging and data archiving—with unlimited data storage in a single location. Docking stations require a demand flow regulator (stock # 71679) and calibration gas cylinder (stock # 55815); up to 10 stations can share one set of calibration equipment.
Includes: AC adapter, 6-ft USB cable, USB flash drive, 5-ft Ethernet cable and 10-ft exhaust tubing.
