Features

Class 1

in accordance to IEC 61672-1

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

OLED display

for full color and high contrast

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. 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.

Auto Calibration

for convenience acoustic calibration

The norms and standards impose the requirement to calibrate the measurement channel before each measurement or measurement session and after the measurement as well for result verification purposes. 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.

Applications

Occupational Noise

noise measurements at work places

The meter is suitable for noise at work measurements in accordance to standards such as ISO 9612, OSHA, MSHA and ACGIH. The TIME HISTORY LOGGING of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved on a 16 GB microSD card (upgradeable to 128 GB). SVAN 971 measures broad-band results with all necessary weighting filters as well as 1/1 octave or 1/3 octave band filters. The audio events recording allows to listen and recognize noise sources.

Environmental noise

periodic outdor measurments

SVAN 971 can be used for environmental measurements even for periodic outdor measurments. The ease of use and fast configuration are ones of the biggest advantages of SVAN 971. Audio events recording and frequency analysis in 1/1 or 1/3 OCTAVES are ideal for noise sources recognition. With optional accessories SVAN 971 can be upgraded to a noise monitoring station.
