The SV 977D has a built-in Bluetooth® interface for wireless connection with with smart-phone applications like Building Acoustics Assistant that extends measurement capabilities dedicated for building acoustics.
One unique feature of the SV 977D is ultrasound measurement band up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Ultrasound is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures.
The SV 977D can be also used as the vibration level meter – simply by connecting a cable and a vibration sensor.
