The RKI GX-Force is a personal 1-4 gas monitor with a strong internal sample pump capable of a 100-foot sampling range. Weighing only 9.8 ounces, it can monitor the standard confined space gases (LEL combustibles, oxygen, carbon monoxide, and hydrogen sulfide) while remaining compact and easy to carry.

The GX-Force features two operating modes: Normal Operating mode for confined space and safety monitoring, and an alternate mode for specialized applications. It operates for 30 hours on a Li-ion battery and includes a large LCD display with auto-backlight in alarm conditions. The microprocessor continuously checks for sensor connections, low battery, circuit trouble, low flow, and calibration errors. Calibration and bump test intervals are user-adjustable, with options to alarm or lock out upon expiration. The unit is water and dust resistant (IP67), impact resistant, and intrinsically safe.
