Bruel & Kjaer Type 2270 Vibration Analyzer/Sound Level Meter

Description

An advanced, dual-channel, hand-held analyzer and sound level meter that has everything needed to perform high-precision, Class 1 measurement tasks in environmental, occupational and industrial application areas.

Type 2270 is a highly versatile, modular platform with many optional application modules such as frequency analysis, FFT, advanced logging (profiling) and sound recording. Its two measurement channels allow it to perform sound intensity measurements according to IEC 61043, sound power measurements, and two-channel building acoustics measurements.

Features

  • Dual-channel input (microphone, sound intensity probe, accelerometer or direct signal) 
  • 4.2 Hz-22.4 kHz broadband linear frequency range with supplied microphone Type 4189
  • 16.6 - 140 dB A-weighted dynamic range with supplied microphone Type 4189
  • Inputs: AC or CCLD, External Trigger
  • Outputs: Generator and Headphone
  • Communication via USB, LAN, or GPRS/3G modems 
  • USB 2.0 host for connection to printer, GPS, weather station, modem
  • Plug-in rechargeable Li-ion battery (> 8h operation)
  • Photo annotations with built-in camera

Specifications

Specifications apply to Type 2250/2270 fitted with Microphone Type 4189 and Microphone Preamplifier ZC-0032 and used as a single channel instrument, indicated as Single Range, unless otherwise stated. For Type 2270 used as a dual-channel instrument measuring both channels simultaneously, the full measuring range is covered in two ranges. High Range indicates the least sensitive range and Low Range indicates the most sensitive range.
