The SV971A is the newest class 1 sound level meter in the 971 series. The appearance of the 971 series on the market changed the perception of class 1 sound level meters. The small size and weight are now appreciated by professionals who carryout measurements with a hand-held instrument. The new model has been fitted with a new microphone with a large dynamic range of 120 dB and a low-power Bluetooth for connection with mobile applications.
