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.

Introduction 2250 Light combines renowned Brüel & Kjær measurement excellence and the Type 2250 platform’s ease of use, in an efficient and versatile sound measurement instrument. Whether you are addressing workplace noise compliance, environmental noise assessment, or product noise certification, 2250 Light offers the functionality to meet your requirements. A unique user-interface makes your measurements easier to perform with results that are easier to analyze and report.

Sometimes noise levels in the workplace vary dramatically, and perhaps irregularly. To assess this kind of noise it is helpful to measure and analyse a noise profile – a measurement that shows how the sound varies with time. The Logging option for 2250 Light provides this capability in a naturally intuitive way, using simultaneous views of the complete profile and a ‘zoomed-in’ 100-second ‘window’. Set up to five different user-defined markers anywhere in the profile, to identify noise sources or events.

For the precise timing of noise events, an alternative ‘Fast Log’ view gives you either or both of the LAF and LAeq results for 100 ms intervals. In either the fast log, or profile view, you can define up to five different markers anywhere in the profile, to identify noise sources or events.

Sound Level Meter Software for 2250 Light – BZ-7130 SLM Module Fig. 2 The large numeric display - ideal for a spot noise enforcement check 2250 Light comes with the Sound Level Meter Software for 2250 Light included. This makes 2250 Light into a versatile broadband sound level meter; it complies with the latest international standard (IEC 61672–1) as well as previous international and national standards. All quantities are measured at the same time.
