SVANTEK Class 1 Urban Noise Monitoring Terminal SV 303
SV 303 is a next-generation Class 1 noise monitoring terminal engineered for precise, real-time urban sound assessment in smart city environments. The instrument ensures full compliance with IEC 61672-1:2013 and IEC 61260-1:2014 standards, delivering highly accurate measurements across a wide LAeq range from 30 to 130 dB. Robust operation in temperatures from -20°C to 60°C and up to 95% humidity makes SV 303 ideal for year-round, multipoint monitoring in any urban climate. Seamless system integration via USB and UART interfaces enables flexible deployment and compatibility with existing environmental monitoring networks. Affordable, reliable, and easy to install, SV 303 empowers city planners and environmental managers to control noise pollution and create healthier, more livable urban spaces.
