ADVANCED POLLUTION INSTRUMENTATION A Teledyne Technologies Company Model T750 Portable Gas Calibrator The Model T750 is a portable, microprocessor based calibrator for precision gas analyzers. Using highly accurate mass flow controllers combined with compressed sources of standard gases, calibration standards are provided for multipoint span and zero calibrations. The T750 is housed in a high-density, molded travel case which includes an integral handle and wheels for durability and ease of use in the field. The Model T750 can be equipped with an optional UV ozone generator for accurate, dependable ozone calibrations, and production of NO2 when blended with NO gas in the included, internal gas phase titration (GPT) chamber. An optional photometer allows even more precise control of the ozone generator giving accurate and dependable ozone calibrations and enhanced GPT. A number of calibration sequences may be programmed into the non-volatile memory of the Model T750, covering time periods up to a year ►► Generates precise calibration gases for ►► Large, vivid, and durable color graphics display with touch screen interface ►► Front panel USB ports for peripheral devices and firmware upgrades ►► Nested sequences (up to 5 levels) ►► Software linearization of mass ►► 3rcl MFC for wide dynamic range ►► Gas phase titration chamber (GPT) All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, and flexible I/O. All instrument set up, control and diagnostic information is available through the front panel, or via RS232, Ethernet, or the optional USB com port, either locally or by remote connection using the included APIcom™ Free Customer Support by telephone and email for the life of the instrument ►► Ozone generator and photometer allow use as a primary or transfer standard Inlets for external ozone reference
