Chemiluminescence NO Analyzer - Eco Physics CLD 88Y

Chemiluminescence technique is the leading measurement method for detecting nitrogen oxides worldwide. The Eco Physics CLD 88Y et is a vacuum chemiluminescence Nitric Oxide analyzer with a digital display of the concentrations and diagnostic messages. This 800 series analyzer is modularly designed to allow the incorporation of the vacuum pump and thermal ozone scrubber inside the case of the analyzer. It has fast response time, unheated, ambient level chemiluminescence effect with a single reaction chamber. External restriction option (e) and shut off valve (t) provide for flexibility in sample flow rates.
