Model T703U PhotometricO3 Calibrator - 1

ADVANCED POLLUTION INSTRUMENTATION A Teledyne Technologies Company 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 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. ►► Transfer standard for calibration ►► Ultra-low ozone capability - ►► Large, vivid, and durable color graphics display with touch screen ►► Front panel USB connections for peripheral devices and firmware ►► 12 independent timers for sequences ►► Nested sequences (up to 5 levels) ►► UV Lamp Feedback modes: current control; reference detector control; photometer control ►► Internal zero air pump (optional) Flow adjustable from 1 LPM to 5 LPM (with internal zero air source) Flow adjustable from 1 LPM to 15 LPM (with external zero air source) ►► High Flow/High Output capability ►► Inlets for external ozone reference Free Custom&r Support by t&l&phon& and email for the life of the instrument
