Svantek SV 307 Noise Monitoring Terminal
The SV 307 is a new Noise Monitoring Terminal (NMT) dedicated for permanent noise
monitoring. The SV 307 integrates Class 1 sound level meter with a modem in the removable
waterproof housing. The SV 307 is equipped with a new MEMS microphone with a life-time
warranty. The measurement data is stored on the microSD card.
The SV 307 is designed for permanent noise monitoring, it has been equipped with a patented
double self-system check: an inbuilt reference sound source producing 100dB at 1 kHz plus real-
time check based on reference microphone.
The waterproof housing of SV307 can be removed to get an access to the user interface with a
colour display and keypad. The SV 307 has an internal Li-Ion battery and interface for
connecting solar panels. A waterproof mains adapter for charging the battery and powering the
station is also included.
SvanNET cloud service monitors the wireless communication, powering and access to the SV
307 data. The scope of the basic SvanNET can be extended with multipoint project management
that offers data storage in the cloud, data sharing, advanced alarming and reporting
features. SvanNET is an on-line solution which means it doesn’t require software installation and
is accessible through a web browser. The responsive design enables use of SvanNET on various
devices such as smartphones or tablets.
