SOUND AND VIBRATION

1. SVAN 971 – Class 1 Sound Level Meter:

VAN 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.

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.

2.  SV 973 – Class 2 Sound Level Meter

SV 973 is a Class 2 sound level meter with a wide frequency range up to 10 kHz. The unique feature of the SV 973 is the microphone in MEMS technology with a lifetime warranty. The meter’s measurement range from 25 to 128 dB enables its use in industrial and environmental noise measurements.
For measurements of noise at work, the intelligent sound exposure meter function limits the frequency range to 10 kHz and shifts the dynamic measuring range of sound level meter to 141 dB Peak. The instrument is easily calibrated in the field using an acoustic calibrator as the calibration begins automatically when the microphone is inserted into the calibrator. The SV 973 can measure broad-band results with all the necessary weighting filters as well as 1/1 octave or 1/3 octave band filters. Audio events recording function works together with sound level meter mode. The data are stored on built-in 8 GB memory and can be easily downloaded to a PC using the Supervisor or SVANPC++ software.

Features:

  • SV 973 Sound Level Meter is CLASS 2 instrument in accordance to IEC 61672-1:2013
  • Microphone in MEMS technology with lifetime warranty
  • Sound exposure meter mode with measurement range up to 141 dB
  • Wide frequency range up to 10 kHz
  • Automatic calibration
  • OLED display
  • Noise sources recognition with 1/1 and 1/3 octave and audio recording
  • RT60 reverberation time measurement in 1/1 or 1/3-octave bands in accordance to ISO 3382

4.  SVAN 958 4 channel Sound and Vibration Meter/Analyser

SVAN 958A Class 1 Four-channel Sound & Vibration Analyser is dedicated for all applications that require simultaneous class 1 sound and vibration assessment. Each of four input channels can be independently configured for sound or vibration detection with different filters and RMS detector time constants giving users an enormous measurement flexibility. The real advantage of SVAN 958A is the capability to perform advanced analysis simultaneously to the level meter mode. In practise this allows the user to obtain broad-band results such as Leq, RMS, LMax, LMin, LPeak together with four-channel analysis like FFT or octave band analysis.

List of available analyser functions includes FFT, 1/1 or 1/3 octave, cross spectra, sound intensity, RT 60 and more. The 4-channel time-domain signal recording to .wav format is available as well as an exceptional feature!
