GX-3R
GX-3R
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. It simultaneously monitors and displays LEL combustibles, O2, CO (H2 compensated CO also available), and H2S.
It represents the latest evolution of gas detection technology utilizing a new generation of microsensor technology.
Sensor Improvements
- LEL sensor has a unique design with two active filaments in one sensor to increase its resistance to silicone poisoning – a common problem with other previous sensors.
- NEW O2 sensor is electrochemical with a 3 to 5-year life span.
- H2S and CO are now available in a combo microsensor.
The instrument also incorporates compliance testing by activating its 3 LED lights every 30 seconds (adjustable interval) if the instrument has not been bump tested if calibration is due, or if there was a gas alarm event. These LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved.
