Wireless sound level meter – Infra C50
A Class 1 sound level meter that measures ambient sound, the SV-307 allows you to quantify sound volume to the nearest decibel.
Its real-time third-octave band frequency analysis allows you to determine the influence of low and high frequencies on the overall value.
To facilitate compliance with regulatory standards, exceedance thresholds, alerts and transmission intervals can be configured.
