Sound & Vibration Analyser [SVAN 979]
The SVAN 979 Class 1 Sound & Vibration Analyser is our flagship device. Your first impression will be the amazing OLED display which features excellent visibility in all light conditions. The instrument’s lightweight and durable aluminum housing not only gives a sense of a firm grip but also protects the valuable electronic device from damage and any influence from electromagnetic interference.
The SVAN 979 has a very large dynamic range of measurement - over 110dB. It’s high-quality GRAS 40AE microphone allows measurement in the frequency range starting as low as 3 Hz. The measurement path has been designed to allow the use of other microphones should you want to measure very low frequencies or very high levels of noise. The microphone preamplifier has also been reinforced with a collar to protect against mechanical damage. One amazing feature of the SVAN 979 is that if you disconnect the microphone preamplifier then you can use the instrument for vibration measurements - simply connect up a cable and a vibration sensor.
The SVAN 979 has an extensive range of hardware and firmware add-ons that includes built-in Bluetooth®, windscreen infrared detector, direct connections to GPS module, GPRS or Wireless LAN modem or the totally unique built-in vibration shock sensor that warns the user whenever the instrument itself is exposed to vibrations that may influence the noise measurements.
