Product Features
The Svantek SV 307A is a new version of the best-selling monitoring station that comes with the latest MEMS microphone and a revolutionary dual remote system that double-checks the measurement path's accuracy. The microphone comes with an infinite manufacturer's guarantee, which is an extra benefit of this option.
The built-in 4G modem of the SV 307A is used to send SMS and email alarms, as well as measurement data to the SvanNET website, where users can check the results and configuration settings.
The SV 307A is a continuous, remote noise monitor that meets class 1 sound level metre criteria in all weather conditions. The SV 307A measures and stores noise levels, statistics, and spectra, so remote monitoring is automatic.
A GPS is used to synchronise the measurement time. It also has the ability to save triggered audio as WAV files. The measurement data is kept in a 32 GB internal memory and uploaded to the SvanNET Web Service via a 4G modem, where it can be viewed and organised as reports. The SV 307A employs a proprietary system check to continually test microphone operation and to sound an alarm if the microphone fails.
