How it works

The Teledyne API Trace Level Portable Gas Calibrator (Model T750U) uses 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, moulded 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 ultra-sensitive 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.
