Product Overview
The RKI GX-3R Pro 5-Gas Monitor combines standard confined-space gas detection with an additional sensor channel for expanded toxic gas monitoring.
The GX-3R Pro can simultaneously monitor LEL, oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S) and a fifth selectable gas. Its compact, lightweight design makes it ideal for confined-space entry, personal monitoring and industrial safety applications where additional gas detection is required.
The GX-3R Pro also features Bluetooth wireless communication, man-down and panic alarms, audible, visual and vibration alarms, and a rugged IP66/68 enclosure designed for demanding work environments.
Available fifth-gas options include:
HCN • NH₃ • NO₂ • PH₃ • SO₂ • CO₂
