The J.J. Wilbur Company is proud to offer the Teledyne API T703 Trace-Level Photmetric Ozone Calibrator. The T703 is a microprocessor controlled ozone calibrator for precision gas analyzers.  The T703 had 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/0, 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.

The Model T703U comes with NumaView™ Software.  NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.
