Confined Space 4 Gas Monitor
Convenient
- RKI GX-3R is the world’s smallest 4-gas monitor weighing only 3.52 oz.
- Can comfortably be clipped within a worker’s breathing zone (2.2″ W x 2.55″ H x 1.02″ D).
- Simultaneously monitors and displays LEL combustibles, O2, CO (Hydrogen compensated CO also available), and H2S.
Up-To-Date & Durable
- Represents the latest evolution of gas detection technology utilizing a new generation of micro sensors.
- 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.
- New O2 sensor is electrochemical with a 3 to 5 year life span. H2S and CO are now available in a combo micro sensor.
Reliable
- Safety supervisors will appreciate the non-compliance indicator.
- Instrument flashes its 3 LED lights every 30 seconds in the following conditions:
- if the instrument has not been bump tested
- if calibration is due
- 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.
- 30 second interval is adjustable.
