Combining a speaker mounted on a traversing 1-axis arc-type device with a dummy head and test subject on a rotating chair makes it possible to set a sound source at any position horizontally or vertically around the head. This enables automated measurement of all positions along a circumference for head-related transfer functions (HRTFs).

MT-3000 TYPE S-T3 traversing device for air-flow measurement

The MT-3000 TYPE S-T3 is designed with a truss structure that suppresses turbulence (along the vertical axis) when measuring slight wind velocity, and a running rail positioned at the lowest point, regarded as the lower limit of the driving mechanism.
The device can be installed with one or two 3D wind velocity gauges.

MT-2000 Z-S featuring a multistage screw-type expansion/contraction mechanism

MT-2000 with telescopic mechanism for additional front/rear axis

The MT-2000 Z-S is an MT-2000 device equipped with a compact telescopic mechanism. This device is suitable for measurements and other tasks involving smaller equipment.
