 The Bruel and Kjaer 2231 Sound Level Meter has been the gold standard in sound level measurements for decades. It has earned this position through quality and reliability under the most demanding circumstances. The B&K 2231 is a light weight battery operated sound level meter that makes absolutely no compromises on accuracy or performance. There are many who make sound level meters but very few can match the quality of construction and accuracy of measurements along with the flexibility of the modular accessories.
