The GX-82A and GX-86A can detect a combination of Combustible, Oxygen, and toxic gases (Carbon Monoxide or Hydrogen Sulfide). The GX-82A and GX-86A are enhanced popular designs of the time tested GX-82 and GX-86. These new designs maintain all of the popular features on the original models such as
the unique removable sensor block engineered for extender cables, sample drawing attachable pump capability, and easy to replace "bayonet" style sensors. Controlled by a microprocessor, the GX-82A and GX-86A models provide continuous monitoring for 12 hours on 2 "C" size alkaline batteries, data logging, and autocalibration of all channels simultaneously. All accessories for prior models are interchangeable with the new "A" series instruments. UL classified as intrinsically safe.
