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.
