SV 277 PRO Noise Monitoring

The SV 277 PRO is a professional outdoor noise monitoring station based on the Class 1 SVAN 977 sound level meter, suitable for long-term environmental and compliance monitoring. The system features an IP65-rated weatherproof enclosure with military-grade connectors, a built-in 17 Ah/12V lead-acid battery providing 4–8 days of autonomous operation, and optional solar panel support for extended deployment. A built-in 4G modem with SvanNET connectivity enables remote access and data retrieval via mobile devices or tablets from any location. The removable sound level meter functions independently as a handheld instrument, giving users maximum flexibility for both stationary monitoring and on-site inspections. Broadband and 1/1 and 1/3 octave time-history logging capabilities make it well suited for infrastructure projects, environmental noise surveys, and regulatory compliance reporting.
