1Introduction
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
2The Envision® System
The Envision® gas meter is a unique field instrument utilized primarily for the measurement of CH4, CO2,
O2, pressure, temperature, and flow within landfill gas and bio-gas collection systems. The Envision®
gas analyzer package is comprised of two components: the handheld computer and the sensor unit
(Envision®).
2.1 Handheld Computer
Elkins Earthworks® currently offers 4 models of handheld computers that can run the Gas Analyzer
proprietary software to operate the Envision® sensor unit. The handheld computers typically
communicate with Envision® via Bluetooth® wireless technology.

2.1.1 Trimble®Nomad
The Nomad is a highly ruggedized field computer from Trimble. The Trimble
series handhelds are all-in-one field computers for GIS (Geographic
Information System) data collection and mobile GIS applications, combining
a handheld computer powered by the Windows Mobile 6 or 6.1 operating
system. The Trimble series handhelds connect to the Envision® via
Bluetooth® or via serial cable. They come standard with Bluetooth and
802.11 (Wi-Fi). Optional features may also be selected such as GPS, barcode
scanner, and/or an internal camera.
2.1.2 Xplore Bobcat
Xplore’s Bobcat ruggedized tablet is IP65
rated, runs Windows 7, 8.1, or 10 and has a
bright 10” touch screen. It has a battery
life of 8 hours (standard) or 14 hours
(optional dual battery). Wi-Fi, GPS,
Bluetooth, and Ethernet communications
are standard with optional 4G LTE. The
Bobcat has a variety of pluggable ports,
cameras in the front and back and optional
barcode scanner, fingerprint scanner, and
near-field communication. It can survive
multiple drops at a height of 4 feet onto
plywood over concrete.

2.1.3 Juniper Archer 2
The Archer 2 is an IP68 rugged handheld unit from Juniper Systems. It runs the
Windows Embedded Handheld 6.5.3 operating system (includes Windows Office
Mobile) and has a 4.3” high visibility touch screen. It can operate up to 20 hours
on a single charge.
2.1.4 Juniper Mesa 2
Juniper’s Mesa 2, 8.5” x 5.5”, IP68 ruggedized tablet comes with
the Windows 10 operating system and runs 8 –10 hours on a
single charge. It has options for Bluetooth, Wi-Fi, 4G LTE, camera,
GPS, barcode scanner, RFID, and hot-swappable batteries.

2.1.5 Envision® Gas Analyzer
The Envision® gas analyzer houses the gas and pressure
sensors. The gas analyzer utilizes infrared sensors to measure CH4
and CO2. The Envision® uses an electrochemical cell to measure O2
concentration and an accurate thermistor temperature probe to
measure wellhead gas temperatures. Data generated by the
Envision® gas analyzer is relayed to the handheld PC via Bluetooth
or serial cable several times per second.

2.1.5.1 Gas Ports
The Envision® gas analyzer ENV100 and ENV200 models have four (4) ports located on the front of the
unit.
Figure 1 ENV100 and ENV200 Port Labels
Port listing from right to left:
Calibrate/Static/Sample port –This port is used to calibrate the unit with calibration gas, to measure
static wellhead pressure, and to sample for gas quality.
Impact Port –This port is used to generate a differential pressure for calculating flow. Do not connect
pressurized calibration gasses to this port.
Available –This port is used to acquire an available (system) vacuum at the monitoring port. Do not
connect pressurized calibration gasses to this port.
Exhaust –This port is used to exhaust the gasses that are pumped through the sample train for
measurement. Only connect an exhaust hose to this port. Do not apply pressure to the exhaust port.
P a g e | 10
The Envision® gas analyzer ENVAUS model is slightly different in that the yellow “Available” port is now
labeled “Borehole Flow” (see photo below). Instead of measuring available (system) vacuum at this
port, it is used to measure low-level borehole flow instead. The “Calibrate/Static/Sample” port is then
used to measure available (system) vacuum.
Figure 2 ENVAUS Port Labels
2.1.5.2 Cable Ports
Charger port –This port is used to charge the unit with the supplied wall charger. The Envision should
run a full, normal working day without needing to be recharged. Plug the charger in overnight to charge
the unit. It usually takes about 4 hours to fully charge an Envision. The charging circuit will turn off
automatically when the unit has reached a full charge. Do not plug the charger into the unit in an
explosive environment.
Thermistor Port –The wired thermistor plugs in to this port. If you have purchased a wireless
(Bluetooth) thermometer from Elkins Earthworks, it may be used in place of the wired thermistor.
PDA Port –The PDA port may be used to directly connect the Envision to a handheld device (with a
serial port) if Bluetooth is unavailable or not working correctly. A standard 9 pin serial cable may be
used.
