DESCRIPTION
The RKI Model GX-82A detects combustible gas (LEL), oxygen
deficiency (O

), and carbon monoxide (CO) or hydrogen sulfide
(H

S). See Table 1 for standard detection ranges for these gases. Gas
detection features include distinctive alarms for dangerous gas
concentrations, time-weighted averaging and short term exposure
limit for toxic gases, and logging of detection data.
The GX-82A has a rugged plastic housing, touch-pad control panel,
and a back-lit dot matrix LCD. The included carrying case protects the
instrument and allows hands-free operation for the user.
The GX-82A is easy to adjust and maintain, with user-replaceable
batteries and sensors. The microprocessor control enables the user to
display a comprehensive listing of gas levels detected and other
related data.
