SVAN 277 pro
Noise Monitoring Station
SV 277 PRO is an outdoor monitoring system based on SVAN 977 Class 1 sound level meter. The IP 65-rated case contains a lead-acid battery which operating time can be easily extended by connecting an external battery or a solar panel. The intelligent charging unit enables use of a solar panel without expensive controllers or heavy batteries. The case is fitted with very robust, waterproof connectors (military standard) and is supplied with an IP 65 external power supply. The light-weight microphone protection kit can be easily installed on a mast with standard mounting threads. All accessories fit conveniently into a second carrying case. The system provides broad-band results such as Leq, Max, Min and Peak with all standard weighting filters together with an incredible time-history logging feature with two adjustable logging steps. The broad-band results can be recorded SV 277 pro Noise Monitoring Station in three acoustic profiles which enable measurements to be taken with 3 different filters (e.g. A, C, Z) as well as 3 different detector time constants (e.g. Fast, Slow, Impulse). The SVAN 977 can be easily removed from the case and used as a hand-held sound level meter. The monitoring station uses a 3G modem for the remote communication with Internet. SvanNET, a relay server, supports the connection between PC and station. The SvanNET allows the usage of all types of SIM cards with the system, regardless if they have public or private IP. The connection over the SvanNET allows users to use a mobile phone or tablet to check the status of the noise monitoring station.

SvanPC++ Remote Communication software package offers advanced features such as
automatic data download, CSV and HTML data publishing as well as FTP upload.
The SvanPC++_RC module supports configuration of the monitoring station as well as
configuration of advanced alarms that combine triggers based on time with noise thresholds.
It can be activated at any time by entering the activation code.
SvanPC++ Environmental Monitoring is designed for post-processing of data recorded by
monitoring station. The module offers a powerful calculator and an automated noise event
finder for noise source identification. Thanks to its “Projects” functionality, SvanPC++_EM
allows to combine and compare data from multiple measurements as well as create and save
reports in MS Word™ templates. It can be activated at any time by entering the activation
code.
The option for 1/3 OCTAVE REAL-TIME ANALYSIS allows the analysis of the noise frequency
contents. The statistical analysis in 1/3 octave band is used for verification of noise sources in
the environment. It can be activated at any time by entering the activation code.
The option of TIME DOMAIN SIGNAL RECORDING to WAVE format works during
measurement and is logged in parallel to a time history. Once downloaded to PC it can be
played back. Settings such as triggers or recording time are adjustable.
In addition to audio play-back, WAVE file can be post-processed in SvanPC++ software that
provides calculation of overall results such as Leq, Lmax, Lmin, Lpeak as well as 1/3 octave and
FFT calculations or tonality. It can be activated at any time by entering the activation code.
