O3 Ozone Calibrator , Model T703
Photometric Ozone Calibrator
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 temperate 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. A nearly unlimited number of calibration sequences may be programmed into the non-volatile memory of the T703, covering time periods up to a year.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports either locally or by remote connection using the included APIcom™ software..
