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, barcoding, 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
2 The 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,

P a g e | 8
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.
P a g e | 9
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.

3 Safety
Landfill gas is normally safely extracted from landfills and conveyed to appropriate control
devices. However, during the course of monitoring each extraction point, exposure may occur. As such,
it is important to follow all site-specific safety protocols when monitoring. Working at a landfill typically
requires site specific health and safety plans. While performing monitoring at a landfill, the user should
be aware of the items included in the site specific health and safety plan. It is important to know that
all personal protection equipment and safety protocols as appropriate must be used when using this
instrument. All vents on the meter are designed to exhaust to the atmosphere. Since landfill gas
contains methane, no smoking is permitted while using the instrument. Calibration gases must be
handled with utmost care and with adequate ventilation.
It is the sole responsibility of the user of the Envision® sensor unit and handheld PC to determine the
appropriate location that either unit can be utilized within as monitoring conditions may change. The
Envision® sensor unit handheld PC are not intended for use in confined space entries but for the
continuous monitoring of gasses within a landfill gas collection system.
4 Certification
Envision® model ENV200 has been UL certified for use in
hazardous locations (Class 1, Zone 1, AEx d ib IIA T4) when
connected in accordance with control drawing 1104M200.
Although models ENV100 and ENVAUS are based on a similar
design, these models have not been certified for use in explosive
atmospheres. It is important that this manual be followed closely
and that any repair to the Envision® gas analyzer is made at the
approved Elkins Earthworks® repair facility. Opening the Envision® gas analyzer and breaking the
housing warranty seals may result in voiding the unit’s warranty as well as compromising the unit’s
safety. The charger should not be connected when an explosive atmosphere is present.
The Envision® sensor unit also meets FCC regulations for a Class A Digital Device Part 15, Subpart B,
Sections 15.107b & 15.109b
