SV 303 Noise Monitoring

Overview

The SV 303 is a Class 1 noise monitoring terminal engineered for continuous, real-time noise measurement in urban and environmental settings. Featuring a patented MEMS microphone with a lifetime warranty and continuous self-check system, it delivers reliable long-term measurements without the drift associated with traditional condenser microphones. The SV 303 supports real-time octave and 1/3-octave analysis, optional audio event recording in WAV format, and integrates seamlessly with the SvanNET cloud platform for remote data access and monitoring. Its IP65-rated housing, wide operating temperature range (-20°C to +60°C), and USB-C power with battery backup make it suitable for permanent outdoor deployment on poles or facades. Ideal for smart city noise control programs, environmental compliance monitoring, and multipoint urban soundscape assessment.
