Description

72-0219RK GX-94 Portable Monitor, LEL/O2 by RKI Instruments

The GX-94 is a powerful and economical solution for confined space gas monitoring requirements. For one low price you receive features such as single-button autocalibration of all gases, datalogging with a lunch break mode, continuous operation for 12 hours on only 2 size C alkaline batteries with a dual low battery alarm (warning and fully dead). You also get simultaneous readout of all 4 gases on an auto back-lit LCD display, a high impact RFI shielded housing, user adjustable audible and visual alarm settings, additional STEL / TWA / Ceiling alarms and readouts, as well as peak or average readouts. The GX-94 has proven to be a highly reliable and rugged gas monitor.

This compact portable instrument will monitor for % LEL levels of combustibles, oxygen deficiency, and ppm levels of hydrogen sulfide and carbon monoxide. The GX-94 is also ergonomically designed with a wide, steelbelt clip that positions the instrument's display and visual alarms facing up at the user. There are several sampling options with the GX-94 including its standard diffusion configuration, the attachable battery driven pump or the hand-aspirated pump. A protective, padded, waterproof carrying case is also available which custom fits the GX-94 and all of its accessories in a protective, foam padding. UL Classified as intrinsically safe.
