PRODUCT DATA

Type 2250-L (2250 Light) has been developed specifically for

measuring occupational, environmental and product noise, while

complying fully with all the relevant national and international

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.

Introduction Type 2250-L is built on the core platform of the award winning design of Type 2250 and maintains the renowned Brüel & Kjær measurement excellence and Type 2250 platform’s ease of use in an efficient and versatile sound measurement instrument. Whether addressing workplace noise compliance, environmental noise assessment, or product noise certification, Type 2250-L offers the functionality to meet your requirements.
PAGE 3
Environmental Noise Assessment Applications The tasks for environmental noise measurements are varied, so the instrument you pick for your measurements needs to be flexible, easy to configure, powerful and accurate. Type 2250-L is all that and more, ideal for a simple noise enforcement measurement one moment and ideal for a complex environmental impact survey the next. Type 2250-L with included Sound Level Meter software BZ-7130 is ideal for spot noise enforcement checks.
PAGE 4
Using the Platform Great care has been taken to ensure that the hardware is ergonomically optimal in field use. Similarly, the software design has focused not only on making valid measurements but also on making field use efficient, convenient and intuitive. All user choices for setups (what to measure) and preferences (how to display it) are controlled using easyto-understand lists, that can be expanded and collapsed. No more cluttered displays, choose only the parameters you want to see. Fig.

Sound Level Meter Software for Type 2250-L – BZ-7130 SLM Module Fig. 2 The large numeric display – ideal for a spot noise enforcement check Type 2250-L comes with Sound Level Meter Software for Type 2250-L included. Type 2250-L is a versatile broadband sound level meter that complies with the latest international standard (IEC 61672–1) as well as previous international and national standards. All quantities are measured simultaneously.

Logging Software for Type 2250-L – BZ-7133 With optional Logging Software enabled, Type2250-L becomes a versatile instrument for obtaining time histories. The Logging Software allows you to select freely among the broadband parameters and log them at intervals from 1 s to 24 h. At the same time LAF, LAS and LAeq can be logged at 100 ms intervals. Fig.
PAGE 7
Signal Recording Option – BZ-7226 Signal Recording Option BZ-7226 works with all other applications. In all cases it allows you to make recordings of the actual measured signal. Recordings are automatically attached to the measurement and kept with it, even after transfer of the data to a PC. One purpose of the Signal Recording Option is to let you record the measurement signal in order to identify and document sound sources. Automatic gain control is available to allow for any signal level.
