Integrating sound level meter SC-250
The SC-250 is a class 1 sound level meter that can be upgraded to a band spectrum analyser. It is the first integrating sound level meter with measurement protocols and therefore simplifies the process of obtaining results as much as possible.
It guides the user step by step through the measurements. The SC-250 has a large display, where all the useful information for the measurement is presented. The data shown on the screen varies according to the chosen application, so that only the parameters required for each application are displayed.
