Hand-held Analyzer Type 2270

Bruel&Kjaer 2270

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
  • ...and more

The unmistakable look and styling of Type 2270 with it’s black background keyboard and high resolution colour touch screen can overshadow a number of more discrete yet equally significant distinctions which make Type 2270 a versatile performer. These are briefly outlined below.

Integrated digital camera

Hand-held Analyzer Type 2270 includes a compact digital camera integrated into the body of the instrument.
The convenience of the integrated camera allows the operator to enhance the measurement report with photo-graphs of room layouts in building acoustics measure-ments, floor covering material used in sound insulation testing, residential apartment proximity to main roads for environmental noise assessment, or QC tested electric motors in vibration testing.

Two channel measurement capability

Hand-held Analyzer Type 2270 is designed with two independent measurement channels and the potential to measure broadband parameters with frequency content at two microphone locations simultaneously. This capability has a number of benefits, not least the obvious one of being able to reduce the measurement time by half in applications requiring multi-point measurements. The following measurement applications are examples of two-channel measurement capability offers significant advantages over single-channel:

  • Simultaneous exterior and interior measurements
  • Sound insulation performance of interior floors and walls
  • Outdoor noise propagation
  • Noise barrier performance verification

Integrated LAN and USB interfaces

Fast and seamless transfer of measure-ment data, recor-dings and photo-graphs is an impor-tant consideration and one that is facilitated by not just one but two high speed interfaces available on Type 2270. Either a USB or LAN interface can be used when the meter is located in close proximity to the PC. When the meter is remote, then the LAN interface allows data download from anywhere within the same LAN network.
