Model T750U
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

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
