B&K Bruel & Kjaer 2250 Multi-function Sound Level Analyzer.

Type 2250-S is a class 1 sound level meter (SLM) that comes with the microphone, preamplifier and basic applications you need to get started with accurate environmental, occupational and industrial measurement tasks.

It is rugged enough for the field yet precise enough to go straight to the lab. Type 2250-S can be expanded with specialized applications such as building acoustics, FFT analysis, tone assessment and noise and vibration.
