SV 277 PRO is a portable monitoring system housed in a waterproof case dedicated for periodic OUTDOOR measurements.
The station is based on SVAN 977 which can be easily removed from the case and used as a hand-held sound level meter.
CLASS 1 noise measurements are performed over a very wide dynamic range over 110 dB from 10 Hz up to 20 kHz.
The TIME-HISTORY of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved on 8 GB microSD card (upgradeable up to 128 GB).
The station can perform real-time frequency analysis in 1/1 OCTAVE bands and save it as time-history data.
The option for 1/3 OCTAVE REAL-TIME ANALYSIS allows the analysis of the noise frequency contents. The statistical analysis in 1/3 octave band is used for verification of noise sources in the environment. It can be activated at any time by entering the activation code.
