Megger Baker MTR105 hand-held static motor tester

The MTR105 is a dedicated Static Motor Tester, offering multiple capabilities in one hand-held device, at an affordable price.

This handy device takes the testing abilities of Megger’s proven IR testing instruments, adding DLRO four wire Kelvin low resistance testing, inductance and capacitance testing to provide a versatile motor tester; all packaged in a robust hand held instrument, which up to now has simply not been available.

The over-moulded case, provides increased protection and robustness, achieving a IP54 weatherproof rating.

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.

Ready for your world!

The IP54 rating provides protection against moisture and dust ingress (including the battery and fuse compartment).  It is CAT III rated 600 V (up to 3000 m).
