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.
