Brüel & Kjær - Model Type 2250-L -Sound Level Meter
A modular Class 1 sound level meter measuring all standard acoustic parameters simultaneously, with frequency analysis, logging and signal recording available as optional application modules. It is designed to address workplace noise compliance, environmental noise assessment and product development. Type 2250-L (2250 Light) is a simplified version of Type 2250 with fewer application modules yet with the same intuitive user interface and measurement precision. It is cloud enabled and supported in the field by Measurement Partner Field App, an advanced companion app. Back in the office, Measurement Partner Suite supports software maintenance, data archiving and viewing and post-processing tasks.

Access your analyzer from anywhere: Type 2250-L allows direct operation through Wi-Fi, mobile connections such as a 3G, 4G, LTE external modem or by using LAN.
And with the new UL-1050 micro-USB “plug and play” solution for Wi-Fi connection in the field, you can remotely control and monitor your analyzer directly from the Measurement Partner Field App at a safe distance without disturbing your measurement.
Control and annotate your measurement with the Field App
The Field App is an advanced companion app to Type 2250-L offering remote instrument control, display, annotation of measurement data and cloud support. It supports all annotation types such as note, voice commentary, image, video and GPS. All annotations are uploaded to Measurement Partner Cloud for merging with the analyzer project in Measurement Partner Suite, transforming the way you work with your Type 2250-L analyzer in the field.
Upload your data to Measurement Partner Cloud
Users who have connected their instrument to the internet can upload their measurement data to Measurement Partner Cloud in the field as soon as the project is saved.
The measurement data is ready and waiting for you (or a colleague) in a cloud archive in Measurement Partner when you get back to the office.
Post-processing with Measurement Partner Suite
Measurement Partner Suite BZ‐5503, in its basic configuration, comes with your hand-held analyzer (see product data sheet). It is Brüel & Kjær`s state‐of‐the‐art data viewing and post‐processing toolbox for environmental noise and vibration. The free, basic configuration provides Measurement Partner Cloud support, Field App support, data archive, preview and export capabilities, software maintenance and online display.
Additional valuable data analysis and post‐processing tools are available on a time‐limited subscription basis. You only pay for what you need, when you need it, with no penalty should your subscription lapse.
Application modules as the need arises
Type 2250-L can host four independent application modules that can be combined to match your needs. These can be ordered factory-installed, or added later as your measurement requirements expand. All application modules are constantly maintained to ensure our sound level meters always comply with the very latest international standards.
Signal recording in high resolution
The signal recording option on Type 2250-L allows you to record the input signal in either 16-bit or 24-bit recording. Use 16-bit recording with Automatic Gain Control when you just need to listen to the signal to identify noise sources, use 24-bit when you want to perform an analysis in Measurement Partner Suite during post-processing.
Touch-sensitive screen and key pad
The large colour screen presents a wealth of information clearly, and is highly customizable, making interaction easy and intuitive. Buttons give single-click access to the most important and frequent commands like start/pause, save, voice comment and event marking.
Smart transducer database
Many transducers can be connected to the instrument, and once one has been used it is remembered by the transducer database. Simply selecting it from the menu automatically attaches all the relevant data to the measurement, including the transducer`s last calibration. Polarization voltage is also set automatically.
Weather station kits
Weather conditions affect the propagation of sound and need be taken into account when measuring noise outdoors. Capture weather data directly on your Type 2250-L using Brüel & Kjær’s two or six parameterweather station kits. Back in the office, post-process your data in Measurement Partner Suite, automatically selecting portions of your data within your weather `window`.
Fast and easy calibration
By simply fitting a Type 4231 calibrator to the sound level meter and pressing the calibration button, it automatically calculates the required correction factor and calibrates itself.
