RKI - Model GX-3R -Confined Space 4 Gas Monitor

SHARE
The GX-3R is a compact multi-gas monitor designed to enhance safety in confined spaces by detecting up to four gases simultaneously. Weighing a mere 3.52 ounces, this versatile device can be easily clipped within a worker's breathing zone, adhering to OSHA guidelines for exposure monitoring. It features the ability to monitor LEL combustibles, oxygen, carbon monoxide (with hydrogen compensation), and hydrogen sulfide. The monitor employs advanced micro sensor technology, including a catalytic combustion LEL sensor that has a dual filament design for increased resistance to silicone poisoning. In the event one filament fails, the secondary filament continues to function. The electrochemical oxygen sensor has a lifespan of three to five years, while H2S and CO are integrated into a combination sensor. A safety feature includes a non-compliance indicator, alerting users with flashing LED lights every 30 seconds if the device needs calibration, hasn't been bump tested, or if there was a gas alarm event.

The GX-3R is the worlds smallest 4 gas monitor weighing only 3.52 ounces and can comfortably be clipped within a worker’s breathing zone (2.2” W x 2.55” H x 1.02” D). It simultaneously monitors and displays LEL combustibles, O2, CO (Hydrogen compensated CO also available), and H2S.

The GX-3R represents the latest evolution of gas detection technology utilizing a new generation of micro sensors. The LEL sensor has a unique design with two active filaments in one sensor to increase it’s resistance to silicone poisoning. If one filament gets poisoned the second filament takes over. The new O2 sensor is electrochemical with a 3 to 5 year life span.  H2S and CO are now available in a combo micro sensor.  

Safety supervisors will appreciate the non-compliance indicator. The instrument flashes it’s 3 LED lights every 30 seconds in the following conditions; if the instrument has not been bump tested, or if calibration is due, or if there was a gas alarm event. The 3 LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved. The 30 second interval is adjustable.

OSHA defines the breathing zone as a ten inch radius around the worker’s nose and mouth, and requires that worker exposure monitoring air samples be collected in the breathing zone. Air sampling filters may be attached to the collar or lapel.  Traditionally this means only a single gas monitor would be small enough for a worker to practically wear a gas monitor ‘In the breathing zone’. Now there is a 4 gas monitor smaller than many single gas monitors.
