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, oxygen, carbon monoxide and hydrogen sulfide.

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).
