Continuous Emission Monitoring System

Our CEMS uses the proven UV fluorescence principle, coupled with state-of-the-art microprocessor technology to provide accurate and dependable measurements of low level S0 2 and NOx.
Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift and a reference detector to correct for changes in UV lamp intensity.
