The Moisture Analyzer offers the unique Advanced Capacitive Transducer (A.C.T.) moisture sensor using state-of-the-art technology to produce a rugged, fast responding, trace moisture sensor. The Carbon Monoxide Analyzer provides an advanced electrochemical sensor with digitized output that is sent to a microprocessor based analyzer featuring: a digital display of carbon monoxide concentrations, up to two software adjustable alarm contacts with visual and audible alarms, and a voltage or current analog output that has user adjustable zero and span. Donaldson Series 200 Oxygen Analyzer utilizes a replaceable electrochemical cell. Advanced features are lower temperature coefficient due to diffusion barrier design, immunity to CO2, and its wide range.
