Sound Level Meters and Vibration Meters

Type 2270-W  2-Channel Hand-Held Analyzer Without Preamplifier And Microphone

Type 2270-W 2-Channel Hand-Held Analyzer Without Preamplifier And Microphone

Type 2270-W is a compact and rugged 2-channel hand-held analyzer that comes without preamplifier. Connect one or two accelerometers and Type 2270-W is a highly accurate vibration meter. The instrument comes with an applications package which enables basic vibration measurements of level and crest factor.

More advanced measurement tasks such as vibration source identification, machinery analysis and troubleshooting, and quality testing and inspection can be added as need arises. For velocity and displacement measurement Enhanced Vibration and Low Frequency Option BZ-7234 can be added.

These tough and precise 2-channel hand-held analyzers have all the capabilities of Type 2250-W plus the benefits of two independent channels, enabling simultaneous measurement of two separate signals, potentially halving measurement time.

You can add your existing preamplifier and microphone (or microphones), to give you the perfect replacement sound level meter (SLM). The addition of specialized applications and accessories expands this instrument’s capabilities to meet your needs for whatever task you have at hand, vibration or noise based.


For use as basic vibration meter with an appropriate accelerometer:

  • Vibration level checks
  • Crest factor measurements

For use as an advanced vibration meter with Enhanced Vibration and Low Frequency Option BZ-7234 and an appropriate accelerometer:

  • Quality testing and inspection
  • Product development
  • Machinery analysis and troubleshooting
  • Building vibration
  • Low-frequency building vibration measurements according to ISO 8041:2005 and DIN standards
  • Maintenance, repair and overhaul (MRO)


The basic applications package includes:

  • 2-channel Measurement Option BZ-7229
  • Sound Leve Meter Software BZ-7222
  • Frequency Analysis Software BZ-7223
  • Tone Assessment Software BZ-7231
  • Noise Monitoring Software BZ-7232

The built-in flexibility of the instrument allows you to add applications and hardware to expand the capabilities beyond the range of the standard SLM, from occupational health and safety (OHS) to building acoustics and reverberation time applications and even to sound power and intensity and noise source identification applications.

Type 2270-W can be used as a Class 1 SLM for general purpose sound measurements to the latest international standards by fitting an appropriate preamplifier and microphone. And by adding applications and accessories, the instrument can be used for a range of noise related tasks, including FFT analysis, noise source identification, sound intensity, OHS assessments, environmental noise logging and assessment, product development and quality control, building acoustics and infrasound (G-weighting) measurements.
