METHOD OF MEASUREMENT:
ELECTROCHEMICAL HYDROGEN SULFIDE SENSORS
The MODEL 3010BX utilizes an electrochemical sensor with a strong sensitivity to trace levels of
hydrogen sulfide. AMI offers customers two sensor options, based on the needs of their applications.
One option can measure trace hydrogen sulfide levels to as high as 200 ppm, while the other option
increases the measurement range to 2000 ppm.
The following table provides the effect on the H2S measurement shown on the Analyzer due to
cross-sensitivity of the listed gases, if the gas is present at a level of 100 ppm.
Common Gases Reading
Methyl Mercaptan 40 ppm
Hydrogen 1 ppm
Carbon monoxide 4 ppm
Uncommon Gases Reading
Nitric Oxide 2 ppm
Sulfur dioxide 18 ppm
Ethylene < 0.8 ppm
Ammonia or amines < 0.1 ppm
Carbonyl sulfide < 0.1 ppm
Carbon disulfide < 0.1 ppm
Chlorine -25 ppm
Nitrogen dioxide -30 ppm
While our sensors have a strong sensitivity to trace levels of H2S, they also have a cross-sensitivity to other
gases.
Hydrogen Sulfide Sensor Range(s)
Low Range 0 –10 ppm, 0 –50 ppm, 0 –100 ppm,
0 –200 ppm
High Range 0 –500 ppm, 0 –1000 ppm,
0 –2000 ppm,
Example: If the sample gas contains 20 ppm of H2S and also contains 100 ppm of hydrogen, the
reading for H2S on the Analyzer will be 21 ppm.

Advanced Micro Instruments has developed and patented key technologies that enable our Analyzers to
deliver the highest levels of PERFORMANCE, RELIABILITY and EASE-OF-USE. These technologies are utilized
by the MODEL 3010BX and are not available on any competitive offering.
Our patented ELIMINATOR CELL BLOCK™ provides a unique sample system
approach that virtually eliminates all potential leak paths while
optimizing flow efficiencies. The sample system and flow-efficient sensor
pocket are machined directly into a solid metallic block and interconnected with
precision-drilled, intersecting gas passages – eliminating the need to use long
lengths of tubing and leak-prone compression fittings. Additionally, a special
engineered 3-way selector valve, metering valve, pressure sensor and flow
meter are all integrated into the machined block.
This approach is far superior than the designs of traditional sample systems that
use multiple off-the-shelf components, numerous compression fittings and long
lengths of tubing that join everything together. The traditional, outdated
approach requires a great deal of space and is prone to leaks.
The Block even provides the user with direct front panel access for installing
and replacing sensors, as well as air calibration feature, without the need for
disassembly or tools.
This powerful software platform comes standard with every MODEL 3010BX
purchase and provides users with access to a full suite of advanced features,
including:
– Settings & logic adjustments for 2-fully independent Alarm Relay Contacts
– Security settings to prevent unauthorized adjustments to the Analyzer via the
front panel
– Changing the analog outputs from 4 –20 mA to 1–5 VDC or vice versa
– Datalogger that records measurement readings, temperature of the Cell Block,
gas pressure, brown-outs and power voltage over a period of 15 days @1-min
intervals (data can be displayed on a graph or in tabular format)
– Error Status Display that alerts users to any error(s) detected by the Analyzer
– Communication with the Analyzer via USB Virtual COMport and Modbus
bi-directional RS485 Communication

STEPS
1. Determine a convenient location to place the Analyzer. The location should ideally
be eye-level.
2. Mount the Analyzer to a wall or bulkhead using the 4 mounting holes or to a 2-inch (5 cm)
pipe using¼" x 2" U-brackets with ¼ nuts.
ANALYZER INSTALLATION
Part I: Mounting the Analyzer
Key Points note: Analyzer weighs 16.0 lbs (7.26 kg)
• The Analyzer can be mounted either indoors or outdoors, where the ambient temperature
remains between 25°F (-3.9°C) and 115°F (46°C)
• For installation, where temperature drops down to -20°F (-29°C), order a MODEL 3010BX
with the factory-installed heater option
• For installation, where temperature drops down to -40°F (-40°C), order a MODEL 3010BX
with the factory-installed EXTREME WEATHER ENCLOSURE and heater option
• When using a solar panel to power the Analyzer, we recommend mounting the solar panel just
above the Analyzer, using the same mast, to serve as a sunshield
WARNING:
The Analyzer weighs 16.0 lbs (7.26 kg) and can pose a risk to the user if dropped.

STEPS
Part II: Electrical Connections for the Analyzer
• Verify your rated power supply matches the operating voltage of your Analyzer before
you begin
• THE MODEL 3010BX is available with either AC or DC Power (you must request your
desired power at the time of your purchase)
Note: Refer to page 48 for the power requirements of your Analyzer.
Note: Both alarm relays are rated for 5A @115VAC or 24VDC.
• Your Analyzer has both 1–5 VDC and 4–20mA isolated analog signals. It has been
setup at the factory per your analog output requirements at the time of purchase.
However, this can be easily changed in the field by following the instructions shown on
page 31
Key Points:
1. Remove the two red plastic protective caps from the ½" NPT conduit holes on the explosion-proof
side of the Analyzer. These plastic caps protect the threads of the unit during shipping.
• We provide 2 (two) separate ½" NPT conduit holes to accommodate all electrical connections.
The first conduit opening should be used for power and alarm relay connections. The second is for
analog output and RS485 connections
Note: AC Power and the opening and closing of alarm relays produce both electrical noise and
large inductive spikes that can have an undesirable effect on the measurement readings. This is why
we provide two conduit openings and strongly recommend separating the sensitive analog signal
wiring from the power and relay wiring.
