This B&K 2245 Sound Level Meter solution is a focused toolset for measuring exhaust noise. Rated IP55, this system is durable enough to be used in the shop or on the street. Whether you are performing stationary exhaust noise testing in a workshop or performing street-side spot checks for law enforcement, this task-focused solution is the ideal tool. Because of the lockable setup, wireless operation capabilities and intuitive interface, a single user can easily preform the measurement and be confident that the data measured will be valid and accurate, with minimal training.

B&K 2245 is type approved by PTB and CEM.

 

Mobile App

Downloading the Noise Partner app to your phone from the App Store® enables the measurement to be wirelessly controlled from a mobile device by a single person – from the driver’s seat of the vehicle or safely on the no-traffic side of the vehicle. Via the app interface, pictures, text and voice notes, and videos can be embedded with the measurements.

 

PC App

When the measurement is finished, the data can be transferred to a PC, wirelessly or with the supplied USB cable. Noise Partner PC software is preconfigured with the tools needed for storing, reviewing and reporting your data.
