Sound Level Calibrator PCE-SC 43-ICA

The calibration frequency for the class II acoustic calibrator is 1000 Hz and is a sinusoidal shape. Compared to other calibrators, this class II sound calibrator has three adjustable sound pressure levels. 94 dB, 104 dB and 114 dB are available and can be selected by pressing a button on the class II sound calibrator. This means that an additional 104 dB sound pressure level is available. With an accuracy of ± 0.4 dB, the class II sound calibrator is particularly precise. This means that the Class II sound calibrator can be used to check sound measuring devices for their accuracy and, if necessary, to adjust them. The class II sound calibrator can optionally be equipped with an ISO certificate.With a battery life of 50 hours, the class II acoustic calibrator has a particularly long operating time. The integrated automatic switch-off automatically switches off the class II sound calibrator after 20 minutes of inactivity. more
