SVANTEK SV 307A - Noise Monitoring Station Class 1
SV307A noise monitoring station is an all-in-one environmental noise monitoring station based on a patented MEMS microphone technology covered by a lifetime warranty. The SV307A Noise monitoring station has been designed for permanent environmental noise monitoring in all weather conditions – it uses smart solutions to control the internal temperature and detect any hardware failures. The new housing is made of strong material that protects internal electronics: class 1 sound level meter with 4G and GPS modems. The measurement data includes noise levels, statistics, and spectra together with audio files that can be triggered on level or time. The advanced triggering provides also the possibility of noise prediction to alarm the user before certain noise levels are reached. For the remote monitoring applications, the SV 307A connects to the SvanNET Service, where all measurement data is accessible via a web interface. Moreover, SvanNET makes it possible to connect to SV 307A to listen to the live noise from the microphone!
The SV 307A is an integrated Noise Monitoring Terminal which means that the sound level meter has been integrated with a 4G modem and outdoor enclosure. The waterproof power supply is also provided for continuous operation in the field. Each SV 307A has its factory calibration certificate. The part of the kit is the new MEMS microphone with a life-time warranty.
