The Megger MTR105 Rotating Machine Tester features a DLRO four wire Kelvin low resistance test, inductance and capacitance tests to provide a versatile motor tester, all packaged in a robust hand held instrument. Additionally the MTR105 incorporates temperature measurement and compensation (for IR tests), motor direction of rotation plus supply phase rotation tests. These new test abilities make the MTR105 a real world, versatile, hand held motor test instrument. The MTR105 comes in an over-moulded case, providing increased protection and robustness, achieving an IP54 weatherproof rating.

Applications for the MTR105:

  • Production tests for new manufactured motors and generators
  • Test repaired and refurbished motors and generators
  • Monitoring and maintenance of in service motors (off line) in the field
