Ultra Trace Fluorescent SO2 Analyser

Model 6400E uses the proven UV fluorescence principle, coupled with state-of-the-art microprocessor technology to provide accurate and dependable measurements of low level S02.
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.

• Ranges are 0-50 ppb to 0-20 ppm, user selectable
