Portable torque monitor for UTMII/UTMV


Product outline

UTMII/UTMV can be easily connected to TM400 with the supplied cable. With the built-in battery, it can be operated even without power source. Using with UTMII with rotary encoder option, torque-angle (or displacement) relationship can be monitored. With the compact body and the high sampling speed, it is ideal for field use.


  • Torque monitor for UTMⅡ/UTMV.
  • With the built-in battery, it can be operated even without power source.
  • Ideal for use with UTMⅡ (square shaft) series with the high-speed sampling at 20kS/s.
  • Easy connection to UTMⅡ/UTMV with one cable.
  • Operation power can be supplied to the UTMⅡ/UTMV (and also to an optional rotary encoder).
  • Torque & rotation speed and torque-angle curve can be monitored.
  • Data recording with memory function and USB.
  • Various display mode: real-time, graph, recorded data, etc….
  • Upper/lower limit & hold function.

Change the display mode by pressing the ESC button
