PRODUCT DATA

Type 2250 is the innovative, 4th generation, hand-held

analyzer from Brüel & Kjær. The design philosophy is

based on extensive research which concluded that the

instrument should be easy and safe to use, while at the

same time incorporating clever features. Type 2250 has

been awarded several prizes for its combination of ex-

cellent ergonomics and attractive design.

Type 2250 can host a number of software modules,

including frequency analysis, logging (profiling) and re-

cording of the measured signal. These are available

separately at any time – or you can order a fully pre-

configured instrument from the factory.

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

areas. As a result, you get the functionality you need

now, plus the option of opening up for more functionality

later – and your investment is securely protected.
