SVAN 971 Class 1 Sound Level Meter is an extremely small instrument with options for 1/1 & 1/3 octave analysis. The instrument brings unprecedented state of the art technology to a SLM of this size.The user interface makes both configuration and measurement easier than ever before. For those who don't have time to work with measurement settings, SVAN 971 offers extremely simple operational mode with Start/Stop. This innovation makes the SVAN 971 an ideal choice for many applications including industrial hygiene noise, short term environmental noise, acoustic consultants, technical engineers and general noise measurements. Another exceptional feature is built-in self-vibration monitoring providing information about level of vibration that influences the measurement results.

The SVAN 971 provides broadband results with all required weighting filters plus 1/1 octave & 1/3 octave band filters. It also offers an incredible time history logging (capability providing broad band results and spectra with adjustable double (long and short) logging steps). Triggered audio recording is also available whilst logging complete functionality.

The instrument can be easily calibrated in the field using an acoustic calibrator. Insertion of the microphone into a calibrator automatically activates the calibration process and the calibration history is automatically logged. Data is stored on a μSD card and can be easily downloaded to a PC using the provided SvanPC++ software over either USB or RS 232 interfaces. New PC software Supervisor will help SVAN 971 owners to organize data from number of measurements and create measurement reports in a quicker and more efficient way than ever before.
