B&K 2245 Sound Level Meter

B&K 2245 Sound Level Meter – More Than a Basic Noise Measurement Device

B&K 2245 is a task-tailored, IEC 61672-1 class 1 sound level meter (SLM) that delivers confident results with a workflow designed for the real world. Use it as a stand-alone instrument in the field, or connect seamlessly to mobile apps and PC software to enable remote measurement control and display, capture rich context like photos and video, and streamline reporting.

Key features

• Task-tailored versions: Available in five versions for exhaust, environmental, workplace, and product noise, in addition to the core B&K 2245-N version for general use.
• Convenient, one-handed operation: Seven easily accessible buttons, ergonomic design, a bright color LCD that clearly shows level and measurement status, and 360° status light-ring visible from any angle for clear measurement feedback.
• Rugged for field work: Robust rubberized housing for a secure grip, with IP55 dust- and water-resistance.
• Wide single measurement range: 23.2 – 140.3 dB(A) from noise floor to maximum level.
• Input correction filters: The configured solution (instrument + included windscreen and software) provides windscreen auto-detection and functions that correct the frequency response to compensate for the sound field and accessories.
• Wireless connectivity: Built-in Wi‑Fi^® and Bluetooth^® Low Energy (BLE) to quickly connect with dedicated iOS/Android apps and PC software for seamless measurement control, data analysis and documentation.
• Steady data management: Automatic storage of measurements and annotations to the instrument’s 16 GB internal storage. Alternatively, you can set up the instrument to automatically back up data to a network or USB storage media (including NAS).
• Integrated context capture: With built-in GPS to add time and location data to your measurements.
• Full-day monitoring: The instrument’s Li‑Ion battery typically provides more than 13 hours of operation when Wi-Fi is enabled.
• Firmware variants that keep you compliant: In countries like Germany and Spain, where a WELMEC-compliant instrument is required for legal metrology, a WELMEC firmware variant for that country is provided. Otherwise, a standard firmware variant is also available.

Typical applications

• General noise monitoring with the standard Noise Partner app. Fast, reliable measurements wherever you need a portable class 1 device or a basic solution for educational and light industrial use.
• Vehicle exhaust noise testing with the Exhaust Noise Partner app. Carry out road vehicle exhaust noise inspections and verify measurements in the field.
• Environmental noise monitoring with the Enviro Noise Partner app. Perform noise measurement surveys the first time, every time without hassle. You can conduct community noise surveys and compliance-oriented spot checks.
• Workplace noise exposure with the Work Noise Partner app. A complete solution for workplace noise surveys, quick checks and regulatory documentation associated with occupational noise assessments.
• Product noise evaluations with Product Noise Partner app. Easy acquisition and reporting of noise emission and sound power levels in accordance to ISO standards or to fulfil CE and other legislative compliance requirements.

Complex noise measurements made simple

B&K 2245 supports broadband sound level measurements with two simultaneous frequency weightings, plus 1/1- and/or 1/3-octave band frequency analysis (for one weighting) to help identify dominant noise sources. You can log parameters at intervals from 1 second to 1 minute, compute spectral and broadband statistics (including five percentiles), and store the full level distribution for later recalculation in HBK apps.

Additional measurement features depend on your installed software licenses.

A flexible SLM solution for full traceability, compliance and integration

B&K 2245 is designed from the ground up to support both iOS and Android™ apps. This enables us to add new features and updates without the need to update the sound level meter. If you need to create and share analysis and reports, data can be quickly and easily transferred from B&K 2245 to your PC and organized intuitively, ready for post-processing using preconfigured, user-friendly tools. This includes automatic measurement transfer to network or USB storage media for documentation and traceability.

For system integrators, a powerful open interface, which allows you to control the instrument and stream data using other systems, is available via the Open Interface for B&K 2245 and HBK 2255 license that is included with all hardware + software bundles.

Find an affordable SLM solution that best fits your needs

The B&K 2245 platform is designed to offer a solid and extremely capable sound level meter in cost-efficient configurations. Each model is a bundle consisting of hardware + a software license, allowing you to simply select a bundle that fits your measurement needs.

The software licences, which are installed on the instrument, automatically enable connection to the various smartphone and desktop apps – and the app versions are free to download.
