Datasheet

The B&K 2250 Class 1 sound level meter is the innovative, 4th generation, hand-held analyzer. The 2250 can host a number of software modules, including frequency analysis, logging (profiling) and recording of the measured signal. These are available separately at any time - or you can order it fully pre-configured.

The combination of software modules and innovative hardware makes the instrument into a dedicated solution for performing high-precision measurement tasks, in environmental, occupational and industrial application area. As a result, you get the functionality you need now, plus the option of opening up for more functionality later.


The Bruel & Kjaer 2250 can fulfill the requirements of the latest standard, IEC 61672–1 and international standards ISO 7196:1995, ANSI/ASA S1.4, S1.42, and S1.43 as well as earlier standards (see the specifications section for detailed compliance information).
