Sound Level Meter Deluxe Kit 15 dBA RMS/140 dBA Peak USB 2.0

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.

• 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 micro SD card
• 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 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 hr on one set of small AAA batteries
• A, B, C, Z, LF weighting filters
• Slow, fast, impulse time constants
• Digital True RMS detector with peak detection, resolution 0.1 dB
• SV 18 detachable preamplifier
• Simultaneous measurement in three profiles with independent set of filters (x) and detectors (y) measurement profiles
• 1/1 octave - real-time analysis in octave band filters, class 1, IEC 61260, filters with center frequencies from 31.5 Hz to 16 kHz
• 1/3 octave - real-time analysis in octave band filters, class 1, IEC 61260, filters with center frequencies from 20 Hz to 20 kHz
• Voice comments - audio records on demand, created before or after measurement, added to measurement file
• 8 push buttons keyboard
• Humidity up to 95 % RH, non-condensed
