We service EVERY product ever made by Enerac and we
stand behind our analyzers and excellent customer service!
Enerac introduced the first model gas analyzer in 1979. Thirty
years of experience in measuring combustion efficiency and
monitoring emissions have given rise to our smallest, most
advanced instruments ever. The Enerac models 500 and
700 can be tailored to suit your specific needs. We invite you
to request a quote and see for yourself.
Enerac Inc. is your source for portable hand-held combustion
and emission analyzers. Enerac gas analyzers are used for a
vast array of applications. The most common applications are
those related to combustion and emission sources such as
boilers, burners, engines, turbines, generators, kilns, dryers,
heaters, ovens, just to name a few. Enerac combustion
analyzers are perfect for both increasing one’s efficiency as
well as for gathering extremely accurate and reliable data for
internal needs as well as for the necessary emissions reporting
requirements found with the local, district, county, state and
federal regulatory agencies.

EMISSION MEASUREMENT TECHNICAL INFORMATION
Enerac is the leading manufacturer of portable emission and combustion analyzers in the world.
The company introduced the model 842 in 1979. This was the first automated combustion
efficiency analyzer ever built.
In 1987 it introduced the Model 2000, the first combustion analyzer with emission measurement
capabilities. Following the success of the Model 2000, an innovative proprietary conditioning
system was added introduced as the Model 2000E, for accurate measurements of nitrogen oxide
and sulfur dioxide emissions based on electrochemical sensor technology.
After a five year joint development effort with City Technology Co., the largest independent
manufacturer of electrochemical sensors, Enerac developed a new series of electrochemical
sensors, under the name of SEM Sensors, that it introduced in its latest portable emission
analyzer, the Model 3000. The Model 3000 is the only portable emission analyzer in the world
that meets the EPA’s new CTM-022 specifications for NOX measurements by portable emission
Thirty years of experience in measuring combustion efficiency and monitoring emissions have
given rise to our smallest, most advanced instruments ever. The Enerac
models M500 and M700 can be tailored to suit your specific needs.
1.0 Applicability and Principle.
1.1 Applicability. This method is applicable to the determination of nitric oxide (NO), nitrogen
dioxide (NO2), and their sum (NOx) concentrations in controlled and uncontrolled emissions
from combustion sources, such as boilers, heaters, engines and turbines. Due to the inherent
cross sensitivities of electrochemical cells, this method should not be applied to other emission
sources or pollutants without first performing both a complete investigation of potential
analytical interferences and a source specific comparative evaluation with published EPA
1.2 Principle. A gas sample is continuously extracted from a stack and a portion of the sample is
conveyed to an instrumental electrochemical analyzer for determination of NO, NO2 and NOx
concentrations. Acceptable electrochemical sensor performance is reaction and capacity dependent,
and requires the selection of a sensor with the correct sensitivity range. Electrochemical sensor
technology can be prone to cross interference, noise, short term drift at low concentrations, and
overloading or saturation at high concentrations. Performance specifications and test procedures must
be followed carefully to ensure reliable data.
Analytical Range. The overall analytical range is determined by the instrumental design and the
availability of sensors with different sensitivity ranges.
