RKI GX-3R Gas Monitor Representing the latest evolution of gas detection technology utilizing a new generation of micro sensors, this gas monitor has an LEL sensor that 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. In addition, the new O 2 sensor is electrochemical with a three to five-year life span. In addition, this detector is small enough for a worker to practically wear in the breathing zone. Features Smallest and lightest four gas monitor Simultaneous detection of four gases Simple two-button operation Non-compliance indicator Alarms: audible, visual, and vibration Three user adjustable alarm levels 25 hours of operation (Lithium-ion battery) Water and dust resistant design, IP66/68 Applications Personal monitoring Confined spaces Refineries/petrochemical Utilities Oil and gas Water/wastewater Fire services Construction
