PRODUCT DATA

2250 Light has been developed specifically for measuring

occupational, environmental and product noise, while

complying fully with all the relevant national and inter-

national 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.

2250 Light comes with Sound Level Meter Software

installed, measuring all parameters simultaneously

within its wide 120 dB dynamic range. For frequency

analysis, add the 1/1- and/or 1/3-octave software module.

For time profile investigation, add the Logging software

module. The optional software modules install easily

and work seamlessly with the Sound Level Meter Software.

Back in the office, USB connectivity lets you use your PC to archive, manage, view or even control 2250 Light,

as well as export your results to software packages such as Microsoft

Excel and Brüel &Kjær Types 7815,

7820 or 7825 for post-processing and reporting.
