    Photometric technology to measure the amount of ozone in the air from ppb levels up to 200 ppm. The 49iQ Analyzer is a dual cell photometer, the concept adopted by NIST for the national ozone standard. Because the instrument has both sample and reference flowing at the same time, a response time of 20 seconds can be achieved.
