SVAN971 Sound Level Meter

SVAN 971 is a CLASS 1 Sound Level Meter in accordance to IEC 61672-1. The meter is TYPE APPROVED in most of the countries around the globe.

The meter is suitable for noise at work measurements in accordance to standards such as ISO 9612, OSHA, MSHA and ACGIH.

It is the SMALLEST Class 1 instrument on the market. The size and weight are very convenient when making hand-held measurements.

The TIME HISTORY LOGGING of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved on a 8 GB microSD card (upgradeable to 128 GB).

The OLED DISPLAY is a full color and high contrast so it can be used in a sunlight or even at night. The OLED technology doesn’t use back-light giving SVAN 971 more battery operating time. The size of display is a perfect compromise between power savings and visibility.

Once the calibration signal is detected, SVAN 971 starts the AUTO-CALIBRATION, saving the calibration data together with the measurement file, both before and after measurement.

The built-in VIBRATION SENSOR informs meter about vibrations that interfere with noise measurements. In addition, the sensor detects the horizontal position of meter so the meter knows when to ROTATE the display.

VOICE ANNOTATIONS (voice comments) before or after the measurements allow easy identification of data files.

SVAN 971 has USB SOCKET which can be used for communication with PC software as well as for powering the instrument from an USB port.

One of the biggest advantages of using SVAN 971 is its POWER EFFICIENCY. It can run up to 24 hours on one set of small AAA batteries.

About SVAN 971

The SVAN 971 is a Class 1 sound level meter in accordance to IEC 61672. The instrument is extremely small but offers unprecedented state of the art technology. For those who do not need to alter the measurement settings, the SVAN 971 has an extremely simple operational mode with only Start/Stop controls. This means that the SVAN 971 is the ideal choice for many applications including industrial noise measurement for health and safety, short term environmental noise monitoring and general noise measurements for acoustic consultants or technical engineers. 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 instrument also includes a built-in vibration sensor that provides information about vibrations that could influence the measurements. The SVAN 971 measures broad-band results with all necessary weighting filters as well as 1/1 octave or 1/3 octave band filters. It also offers time-history logging with two adjustable logging steps. The audio events recording allows to listen and recognize noise sources. The data are stored on a microSD card and can be easily downloaded to a PC using the Supervisor or SvanPC++ software.

What’s inside the SVAN971 kit?

The kit consists of SVAN 971 Class 1 sound level meter with detachable preamplifier SV 18 and high quality omni-directional ACO SV 7052E microphone, compliant to IEC61094-4. The list of accessories includes: SA 22 windscreen, 8 GB microSD card, four AAA batteries, USB cable, and CD with user manual. Each SVAN 971 has its factory calibration certificate and 36 months warranty card.

PC Software for SVAN971

Supervisor software supports data download, instrument configuration and provides complete set of tools for determination of occupational noise exposure from noise level measurements in accordance to all standards using TWA and DOSE such as OSHA, ACGIH, MSHA, NR-15 or NHO-01. The data files from the SVAN 971 can be used for calculation of all required measurement results and uncertainties in accordance to the three measurement strategies described in ISO 9612. SvanPC++ is a PC software supporting functions such as measurement data downloading from instruments to PC, measurement setups creation, basic Leq/RMS recalculation, measurement results in text, table and graphical form of presentation, export data to a spread sheet or text editor applications. New version of SvanPC++ software also supports analysis of wave files from Svantek’s instruments (for example calculation of tonality).
