RKI GX-3R Pro [(LEL/O2/H2S/CO) with Li-Ion battery pack and 100-240VAC charger]
$980.00
Confined Space 5 Gas Monitor
The GX-3R Pro is the world’s smallest 5-gas monitor. 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 sensors. Weighing only 4.58 ounces, it fits in the palm of your hand (2.9” W x 2.6” H x 1.06” D).
The GX-3R Pro utilizes Bluetooth communication to display direct gas readings from the instrument to a phone app, which is available free on either iOS or Android phones.
