    Fitted with a balanced high speed driveline kit. A universal adaptor for diesel or Timesaver adaptor for electric.
  • Protection is built-in against harmonic vibration, torque overload and thermal overload.
  • check
    Bi-rotational - can test either rotation
  • check
    DynoPro 2100S computer & printer (see below)
  • check
    Calibration is an easy one man operation done on site (no need to send away)
  • Unit is portable & on wheels - can easily be floor or rail mounted.
  • check
    The I-300 can test diesel engines, electric motors, gear boxes, transmissions and other high torque/low RPM applications. Other options permit custom-tailoring of the I-300 to your application. In addition, the I-300 can be factory equipped to test unusually high torque/low RPM equipment.
