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.
