B&K Type 2270 Sound Level Meter is our flagship measuring instrument and analyzer. Equipped with two microphones, or two accelerometers, or one of each, B&K Type 2270 offers all the functionality as Type 2250 - with the addition of being capable of simultaneous measurements. In addition, tight phase matching between the two channels, allow Type 2270 to be used as a sound intensity analyzer.
