Model 49i PS Ozone Analyzer Datasheet

The Thermo Scientific Model 49i-PS analyzer is a dual cell photometer, the concept adopted by the NIST for the national ozone standard.

The Model 49i-PS analyzer can operate with ozonator flow rates of up to 6 liters a minute. Because the instrument has both sample and reference flowing simultaneously, a response time of 20 seconds can be achieved.
