SVAN 271 lite
Noise Monitoring Station

SV 271 LITE is an outdoor monitoring system based on typeapproved SVAN 971 Class 1 sound level meter. The IP 65-rated case contains a lead-acid battery which operating life 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 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 971 can be easily removed from the case and used as hand-held sound level meter.

Analizzatore
- Analisi in 1/1 ottava Analisi in real-time in classe 1, conforme alla di IEC 61260, da 31.5 Hz a 16 kHz (opzionale) contemporaneamente ai tre profili (SLM), registrazione time history e audio
- Analisi in 1/3 d’ottava Analisi in real-time in classe 1, conforme alla di IEC 61260, da 20 Hz a 20 kHz (opzionale) contemporaneamente ai tre profili (SLM), registrazione time history e audio


The option for 1/1 OR 1/3 OCTAVE REAL-TIME ANALYSIS allows the analysis of the noise
frequency contents. It can be activated at any time by entering an activation code.

The option of EVENT RECORDING works during measurement and is logged in parallel to time
history. Once downloaded to PC it can be played back. Settings such as triggers or recording
time are adjustable. It can be activated at any time by entering an 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. The module can be activated at any
time by entering the activation code.
