Everything Your CEMS Program Requires
CEMS Experts — the FTIR Specialists
FTIR CEMS are ideal when multiple gases must be measured with high accuracy in challenging environments — cement kilns, glass furnaces, waste incinerators, and wood-fired boilers. As EPA regulations expand to cover more Hazardous Air Pollutants (HCl, ammonia, benzene, formaldehyde), FTIR is increasingly the right technology. We'll help you evaluate if FTIR fits your application and make implementation seamless.
CEMS Experts' technical knowledge of the finer points of Air Pollution Monitoring Systems is superior. They are one whom I have enjoyed working with to solve complicated issues with mutual clients. CEMS Experts' engineers are always professional in appearance and demeanor.— Steven Croghan, Sr. Project Manager – Air Measurements, TRC Companies, Inc.
