MT-4000 for rotation of microphones

Photo of MT-4000

The MT-4000 is an MT-3000 Series system with a free rotation device attached to the tip. Directing a microphone toward a measurement target when transforming the acoustic intensity probe axis or measuring sound power levels can be very time-consuming. The MT-4000, which is an extended MT-3000 TYPE 3 system featuring a rotating axis at the tip, allows computer control of changing direction of microphone and/or sound intensity probe.
