Trace Level Portable Gas Calibrator The Model T750U is a portable, microprocessor based calibrator for precision gas Ultra-stable ozone output to 3 ppb analyzers. Using highly accurate mass flow controllers combined with compressed Ultra-low gas phase titration (GPT) to 3 ppb NO2 sources of standard gases, calibration standards are provided for multipoint span and zero calibrations. The T750U is housed in a high-density, molded travel case which includes an integral handle and wheels for durability and ease of use in the Built-in photometer, ozone generator, and GPT chamber Large, vivid, and durable color graphics display with touch screen interface The Model T750U is designed for the demanding requirements of ultra-sensitive Ethernet, RS-232, and (optional) USB com ports measurements. The ability to calibrate and verify linearity for NO2 levels below 5 ppb is difficult with standard calibrators. To overcome this limitation, the Model T750U ozone generator operates in two modes; a high range with similar performance to the Model T750 ozone generator, and a low range, or “fractional” mode, for producing accurate ozone levels down to 3 ppb. To ensure the highest accuracy of NO2 output, the calibrator measures the ozone concentration prior to performing a Front panel USB ports for peripheral devices and firmware upgrades Nested sequences (up to 5 levels) Software linearization of mass flow controllers (MFC) gas phase titration (GPT), and the range is selected automatically by the Model 3rd MFC for wide dynamic range (optional) T750U based on ozone concentration and flow specified by the user. All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, and flexible I/0. All instrument set up, control and diagnostic Inlet for external ozone reference sources Two year warranty 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™ software. Free Customer Support by telephone and email for the life of the instrument
