SV 271 LITE Noise Monitoring Station

SV 271 LITE is an outdoor monitoring system based on type approved 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.

SV 271 LITE features:

  • SV 271 LITE is a portable monitoring system housed in a waterproof case dedicated for periodic OUTDOOR measurements
  • The station is based on SVAN 971 which can be easily removed from the case and used as a hand-held sound level meter
  • SVAN 971 is a Class 1 TYPE APPROVED sound level meter in accordance with IEC 61672-1 standard
  • The TIME-HISTORY of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved on a 8 GB microSD card (upgradeable up to 128 GB)
  • The light-weight microphone protection kit gives an easy access for calibration with an acoustic calibrator. Once the calibration
    signal is detected, the system starts the AUTO-CALIBRATION
  • The LARGE WINDSCREEN is highly efficient in reduction of a wind noise effects even at high wind speeds
  • Military standard CONNECTORS provide reliable, robust and waterproof cable connections
  • Station uses waterproof CHARGER that is designed for outdoor use

    PANEL. The powering is managed by the intelligent charging unit
  • 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
