Integrating Soundmeter Sc102

The SC102 class 2 integrating sonometer is more than an acoustic measurement instrument since it not only performs the measurements but also the checks and calculations indicated in the standards, to obtain the final result in situ.

It is the first integrating sound level meter with measurement protocols, which simplifies the process to obtain the results to the maximum. Guides the user step by step in carrying out measurements.

This model of sound level meter has a removable preamplifier to be able to carry out noise measurements of both vehicles and machines (pressure and sound power).
