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 Decibel Meter 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 sound level calibrator has a particularly long operating time. The integrated automatic switch-off automatically switches off the class II Decibel Meter Calibrator after 20 minutes of inactivity.
