​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.

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 information is available through the front panel, or via RS232, Ethernet, or the optional USB com port, either locally or by remote connection.

The Model T750 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. ​​​
