standards.

Extensive user studies have been paired with state-of-the-art

technology to make this analyzer a robust, effective and elegant

tool for those applications.

Using the large, high-contrast, touch screen interface, the

analyzer can easily be set up to display and measure just what is

needed from the extensive list of parameters provided by the

analyzer.

Back in the office use the included Measurement Partner Suite

BZ-5503 to manage, view or even control 2250 Light, as well as

export your results to software packages such as Microsoft

Excel

. Measurement Partner Suite BZ-5503, with or without the

optional advanced modules, is the quickest route from

measurement data to finished report.
