Product Overview
The RKI GX-Force Pumped 4-Gas Monitor is a compact sample-draw gas detector designed for confined-space entry, personal monitoring, leak investigation, and industrial safety applications. Its powerful internal pump provides a sampling range of up to 100 feet, allowing users to remotely check an atmosphere before entering a potentially hazardous area.
The GX-Force can simultaneously monitor the standard confined-space gases: combustible gas (LEL), oxygen (O₂), carbon monoxide (CO), and hydrogen sulfide (H₂S). The instrument combines RKI's compact sensor technology with an internal sample pump in a lightweight, rugged package.
Two operating modes provide additional flexibility. Normal Mode is designed for standard confined-space and safety monitoring, while Leak Check Mode can be used for investigating combustible gas leaks in valves, piping, and other equipment.
The GX-Force also features approximately 30 hours of operation in Normal Mode, USB-C charging and data connectivity, data logging, audible/visual/vibration alarms, field-replaceable sensors and filters, and an IP67 water- and dust-resistant enclosure.
Common Applications:
Confined Spaces • Personal Monitoring • Refineries & Petrochemical • Oil & Gas • Utilities • Water & Wastewater • Fire Services • Construction • Leak Investigation
