1 Introduction
Elkins Earthworks® would like to welcome you to the Envision® gas analyzer system. The Envision® gas
analyzer, designed by Elkins Earthworks® is manufactured in the United States. The equipment was
designed for the field technician as well as project managers. The Envision® gas analyzer is a two-part
system, the sensor unit (Envision®) and the handheld computer. This unique pairing makes field
activities more productive by giving the user the ability to expand functionality by using GPS, bar-
coding, and other features that the Windows® operating system can offer.
There are currently 4 models of Envision gas analyzer:
ENV100 – has internal heating pads and is not certified intrinsically safe
ENV200 – does not have internal heating pads and is certified intrinsically safe
ENV200 “B” – same as ENV200 with added capability to measure barometric pressure
ENVAUS – does not have internal heating pads, is not certified intrinsically safe, and has borehole flow
measurement capability
