Model T703U Photometric 03 Calibrator

The Model T703U is a microprocessor controlled ozone calibrator

for precision gas analyzers. Expanded ozone audit levels have

created a need for precise ozone calibration well below the

capabilities of standard calibrators. The Model T703U is designed to

meet the requirements of ultra-low ozone production.

In addition to a high range with similar performance to the Model

T703, the Model T703U has the capability to generate ozone in a

low range, or "fractional" mode, for producing ozone levels down to

3 ppb, with exceptional accuracy. 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. A nearly

unlimited number of calibration sequences may be programmed

into the non-volatile memory of the T703U, 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.
