RKI Instruments GX-3R Multi-Gas Detector Offers
The GX-3R is the world's 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.
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.
The GX-3R represents the latest evolution of gas detection technology utilizing a new generation of microsensors. The LEL sensor has a unique design with two active filaments in one sensor to increase its 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 microsensor.
Safety supervisors will appreciate the non-compliance indicator. The instrument flashes its 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.
