The Kymograph has a spindle 320 x 19 mm OD (12-1/2 x 3/4 in OD) for mounting a cylinder included. The speed range, dependent on circumference of cylinder chosen, is infinitely variable by use of control. The Kymograph is also supplied with out cylinder or stimulator).
Kymograph with Stimulator :
The Kymograph is the same as described above. The built-in square wave stimulator has a maximum output of 25 volts with less than 25 W impedance. The frequency range is continuously variable. The output has three selection: continuous, single pulse by push button and external trigger via the contact arms on the Kymograph spindle. All the controls are located on the front panel.
