Svantek SVAN 971 Class 1 Sound Level Meter

SVAN 971 Class 1 Sound Level Meter is physically small instrument (232.5mm x 56mm x 20mm; 225g), with options for 1/1 & 1/3 octave analysis. The instrument is packed with state of the art technology for SLM of its size.

Ideal choice for applications such as environmental noise, industrial hygiene, acoustic consultants, sound engineers and general noise measurements.

Built-in self-vibration monitoring providing information about vibrations that influenced the measurement results.

Time history logging.

Available option for “triggered audio recording” function, allows audio files to be recorded for playback and identification purposes. A very useful function when numbers alone cannot tell what caused the noise.

Easily calibrated in the field using an acoustic calibrator. Insert the microphone into a calibrator, and it automatically activates the calibration process. Calibration history is automatically logged.

Data is stored on a USB card inside the SVAN 971, and can be downloaded to a PC using the provided SvanPC++ software over USB cable. New PC software Supervisor (Free) will help SVAN 971 users to download, organise data, and create measurement reports quickly.

Application

  • Sound measurements
  • Environmental noise
  • Occupational noise
