GX-3R PRO Confined Space 5-Gas Monitor - DESCRIPTION
by RKI Instruments

The GX-3R Pro is the world’s smallest 5-gas monitor weighing only 4.58 ounces, and fits in the palm of your hand (2.9” W x 2.6” H x 1.06” D). It simultaneously monitors and displays five different gases. In addition to monitoring standard confined space gases, LEL, O2, CO, & H2S, the GX-3R Pro has a 5th channel where you can add infrared or toxic gas sensors. Two of the four sensor slots have interchangeable sensors providing flexible configurations, easily changed in the field.

The GX-3R Pro utilizes Bluetooth communication to display direct gas readings from the instrument to a phone app, free on iOS or Android phones. If there is an alarm event from the GX-3R Pro, you can program automatic notifications and send a text or email messages.


Safety supervisors will appreciate the non-compliance indicator. The 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, or if there was a gas alarm event. The 3 LED lights will continue to flash once every 30 seconds until the resolution of the non-compliance condition. The 30-second interval is adjustable.
