Svantek SV 307A Noise Monitor
Class 1 noise monitor for continuous, remote noise monitoring suitable for withstanding harsh environments.
Svantek SV 307A Noise Monitor Overview
Svantek’s SV 307A noise monitor provides continuous and remote noise monitoring with class 1 accuracy. Its robust construction makes it reliable for use in challenging environments and weather conditions. Utilising the advanced MEMS technology with a patented dual remote system allows the SV 307A to check the measurement path and enhance accuracy in conjunction with the GPS localisation and synchronisation system. Online system check capabilities ensure that the maintenance requirements can be consistently adhered to and the instrument can function optimally.
Data measured by the SV 307A is accessible remotely using either SvanNET or Air-Met Scientific’s LiveSense platform. Both these software options allow data to be transferred from the instrument’s built-in 4G modem to their online portals where data can be easily viewed and managed. With a range of useful data management capabilities including real-time frequency analysis, live audio streaming and triggered audio recordings, interpreting and using the data is straightforward and efficient.
The SV 307A and SV 803 Building and Ground Vibration Monitor are compatible with the AirMetER Series Environmental Monitoring Stations, allowing noise and vibration data to be monitored alongside a wide range of other parameters including gas and dust. All this data can then be conveniently managed through the LiveSense online platform.
