T703 - Photometric Ozone Calibrator Get a Quote

The Model T703 is a microprocessor controlled ozone calibrator for precision gas analyzers. The Model T703 can deliver concentrations from 50 ppb to 5 ppm at flows from 1 LPM to 5 LPM. The Model T703 has two major components; the ozone generating device and the photometer. The ozone generator produces ozone by passing zero air over a UV lamp. Flow rate and lamp intensity are adjusted to deliver a specified ozone concentration by volume. The temperature and pressure compensated photometer, identical to that of the Model T400 ozone analyzer, provides feedback control of the UV lamp intensity, assuring stable ozone output.
