Why ESC Spectrum?

CEMS Analyzer Repairs

ESC Spectrum has performed a variety of CEMS maintenance, repair, and testing services since its founding in 1981 by a field technician. We were the first company to certify a CEMS in accordance with Part 75 regulations and began stack testing and building shelters in 1991.

After decades of experience, we’ve seen it all: our team of experts is well-versed in solving unique challenges. We understand EPA test methodologies, repair analyzers, umbilical systems, and other CEMS equipment and have a deep knowledge of CEMS operations.
