gx 35 and the gx 3r pro

The GX-3R is the world’s smallest
4-gas monitor!

Weighing only 3.52 ounces, it clips comfortably within a worker’s breathing zone. Both the GX-3R and the GX-3R Pro utilize a new generation of micro sensors:

  • The new LEL sensor has two active filaments to increase its resistance to silicone poisoning
  • The new O2 sensor has a 3 to 5 year life span
  • H2S and CO are now monitored by one combination micro-sensor
  • Available with a hydrogen compensated CO sensor (as LEL/O2/CO)
  • Non-compliance indicator
  • The sensors are field replaceable: Easy to change in less than 60 seconds

Weighing only 4.58 ounces, it fits in the palm of your hand! In addition to the four confined space gases (CO, H2S, LEL, O2) the GX-3R Pro has a 5th channel for toxic and infrared sensors that can monitor:

  • ppm of CO2
  • % volume of CO2
  • SO2
  • CO sensor (with hydrogen compensation)
  • HCN, NO2, NH3, or CL2      [COMING SOON, 2020]

Additionally, the GX-3R Pro comes equipped with:

  •  Two interchangeable sensor slots providing flexible configurations
  • Non-compliance indicator
  • Man-down alarm
  • Panic alarm

3 Year Warranty

RKI backs up our quality with a 3-year warranty on the instrument and the sensors for both GX-3R and the GX-3R Pro. We believe gas monitors should be in service for years and not decommissioned after 24 months. If cost of ownership is important to you, then the GX-3R and GX-3R Pro are excellent solutions.
