Introduction - Teledyne T750 User Manual

INTRODUCTION

The Model T750 and Model T750U are portable, microprocessor-controlled calibrators for
precision gas analyzers, with the T750U designed for precision trace-level gas analyzers.
Using a combination of highly accurate mass flow controllers and compressed sources of
standard gases, calibration standards are provided for multipoint span and zero calibrations.
The T750 can be equipped with an optional, programmable ozone generator that includes
an internal gas phase titration (GPT) chamber for accurate, dependable ozone calibrations.
This option can also include a UV photometer option for even more precise control of the
ozone generator. The standard T750U has all these features and is designed for producing
stable ozone concentrations not only in a high range mode similar to the T750, but also in
a low range or fractional mode for producing much lower levels of ozone down to 3 ppb.
As many as 50 independent calibration sequences may be programmed into these portable
calibrators, covering time periods of up to one year. Sequence setup is simple and intuitive,
and may be actuated manually, automatically, or by a remote signal. The sequences may
be uploaded remotely, including remote editing. All programs are maintained in non-
volatile memory.
The T750 and the T750U provide fast response, repeatability, overall accuracy and ease of
operation, and may be combined with a Teledyne API Zero Air Generator to provide the
ultimate in easy to use, precise calibration for your gas analyzers.
