2270 Datasheet Accessory Kit
‚ÄčThe Bruel & Kjaer 2270 Sound Level Meter and Vibration Analyzer is a 2-channel handheld vibration and sound measurement device which features a dynamic range of over 120 dB and operates over a broadband linear frequency range of 3 Hz - 20 kHz. Bruel & Kjaer 2270 test instruments measure sound and vibration simultaneously on two independent channels, utilizing the measurement power of two microphones and two accelerometers to reduce and potentially halve measurement time. 

Technicians rent and rely on 2270 units for essential analytical tasks in numerous applications, including frequency analysis, logging/profiling and signal recording. Being a dual channel analyzer, the Bruel & Kjaer 2270 also allows users to perform intensity and sound power measurements for dual-channel building acoustics applications. USB, LAN or GPRS/3G modem compatible with customizable display setup.
