GX-3R Four Gas Personal Monitor Overview
The GX-3R one-to-four gas personal monitor picks up where the GX-2009 left off. It’s the world’s smallest four-gas personal monitor, weighing only 100 grams, and can comfortably be worn within the worker’s breathing zone (55mm W x 64mm H x 26mm D). It simultaneously monitors and displays LEL combustibles, O2, CO (Hydrogen compensated CO also available), and H2S.
The Breathing Zone
Optional Health and Safety defines the breathing zone as a 25cm radius around the worker’s nose and mouth and requires that worker exposure 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 wear ‘In the breathing zone practically’. Now there is a four-gas monitor smaller than many single-gas monitors.
Sensors
This instrument represents the latest evolution of gas detection technology utilising a new generation of microsensors. The LEL sensor has a unique design with two active filaments in a single sensor to increase its resistance to silicone poisoning. If one filament gets poisoned, the second filament takes over. The new O2 sensor is electrochemical and has a 5-year lifespan. H2S and CO are now available in a combo microsensor.
Non-compliance indicator
Safety supervisors will appreciate the non-compliance indicator. The instrument flashes its 3 LED lights every 30 seconds, if the device has been exposed to a gas, has not been bump tested, or calibration is due. The 3 LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved.
