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 straight hours on only 2 size
C alkaline batteries with a dual low battery alarm (warning and fully
dead), 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 is a lot of gas monitor
for its price.
This compact and rugged 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, steel-belt clip that positions the instrument’s display and
visual alarms facing up at the user. There are several sampling options
including the GX-94 in its standard diffusion configuration, or utilize
its attachable battery driven or hand aspirated pump for a quicker response.
A sturdy, 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.
