Sound Level Meter – Type 2270

Overview

2270An advanced, dual-channel, hand-held analyzer and sound level meter that has everything needed to perform high-precision, Class 1 measurement tasks in environmental, occupational and industrial application areas.

Type 2270 is a highly versatile, modular platform with many optional application modules such as frequency analysis, FFT, advanced logging (profiling) and sound recording. Its two measurement channels allow it to perform sound intensity measurements according to IEC 61043, sound power measurements, and two-channel building acoustics measurements.
