BRÜEL & KJÆR SOUND & VIBRATION MEASUREMENT A/S - DENMARK
Hand -held Analyzer Type 2270 is designed as an advanced solution for sound and vibration measurement, analysis and recording.
Built on the award winning Type 2250 design, Type 2270 continues to blend the best of today’s hand-held technologies with over 60 years of experience in sound and vibration measurement solutions.
The design philosophy of Type 2270 is to speedily present the operator with the measurement result in the palm of his hand.
This philosophy is carried through to each of the application modules currently available for Type 2270:
Sound Level Meter application
Real-time frequency analysis
Logging (noise level profiling)
Sound and vibration recording
FFT analysis of sound and vibration
Reverberation time measurement
