Bruel & Kjaer 2270 Sound Level Meter and Vibration Analyzer

The Bruel & Kjaer 2270 Sound Level Meter and Vibration Analyzer is a 2-channel handheld vibration and sound measurement device that has over a 120dB dynamic range and operates over a 3Hz - 20kHz broadband linear frequency range. It measures sound and vibration simultaneously on its two independent channels, reducing (potentially halving) measurement time. This device also performs numerous analytical tasks for frequency analysis, logging/profiling, and signal recording.
