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 analyzers. 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.
