Trace Level Portable Gas Calibrator

The Model T750U is a portable, microprocessor based calibrator for precision trace-level 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 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 field.

The Model T750U is designed for the demanding requirements of trace-level 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 gas phase titration (GPT), and the range is selected automatically by the Model 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 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.

Upon request, the Model T750U is available with NumaView software. NumaView Remote PC software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView software.
