TYPE 2270-S


B&K Type 2270-S is a two-channel sound level meter and analyzer, designed for class 1 measurement accuracy on both channels.

Type 2270-S is a compact and rugged class 1 type-approved 2-channel sound level meter with all the capabilities of Types 2250-S and -2250-W, plus the benefits of two independent channels. This allows the meter to measure simultaneously with two microphones, two accelerometers or one of each, potentially halving measurement time.

With the addition of specialized applications, the instrument’s functionality can be expanded to meet whatever task requirements you have, for noise or vibration assessments, including specialized applications for building acoustics, FFT analysis, tone assessment, noise source identification, sound intensity, industrial applications and vibration measurements.
