Model 700E
Mass Flow Calibrator
The Model 700E is a microprocessor based calibrator for precision 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 checks. Up to 4 gas sources may
be used.
In addition, the Model 700E can be equipped with an optional built-in,
programmable ozone generator for accurate, dependable ozone
calibrations and to produce NO2 when blended
with NO gas in the
internal GPT chamber.
A multi-point linearization curve is used to control the generator to
assure repeatable ozone concentrations, and the optional photometer
allows for even more precise control of the ozone generator, for both
calibrations and Gas Phase Titrations (GPT). To ensure even more
accurate NO2 output, the calibrator with photometer option measures the
ozone concentration prior to doing a GPT.
As many as 50 independent calibration sequences may be programmed into
the M700E, covering time periods of up to one year. The setup of
sequences is simple and intuitive. These sequences 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 M700E design emphasizes fast response, repeatability, overall
accuracy and ease of operation. It may be combined with the Model 701
Zero Air Generator
to provide the ultimate in easy to use, precise calibration for your
gas analyzers.
