BPIT, Inc. - T700U Dynamic Dilution Calibrator

T700U Dynamic Dilution Calibrator

By: Teledyne Instruments API


The Model T700U is a 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 checks using up to 4 gas sources.

In addition to the features of the Model T700, the Model T700U is designed for the demanding requirements of ultra-sensitive measurements. The ability to calibrate and verify linearity for NO2 at levels below 5 ppb is difficult with standard calibrators. To overcome this limitation, the Model T700U ozone generator operates in two modes; a high range with similar performance to the Model T700 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 GPT, and the range is selected automatically by the Model T700U based on ozone concentration and flow specified by the user.
