SV104IS

The SV 104IS is an intrinsically safe noise dosimeter with a robust 1/2” MEMS microphone enabling easy calibration using most commonly available acoustic calibrators. A new microphone has a large dynamic range of the 90 dB which allows to measure noise from 60 dBA Leq to 140 dB Peak. The long list of microphone advantages includes also the auto-calibration feature and TEDS memory that stores the calibration info in the microphone itself. The auto calibration means performing acoustic calibration automatically once the microphone is inserted into the calibrator.
