The Megger Baker MTR105 is a dedicated Static Motor Tester with Megger’s tried and trusted suite of insulation resistance tests (IR), plus all the great traditional features and reliability of Megger’s testers. It is an OFF LINE motor tester that can be used on small to medium sized rotating machines, typically up to 500 hp.

The MTR105 takes the test abilities of Megger’s proven IR test instruments adding 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, which up to now has simply not been available.

Additionally the MTR105 incorporates temperature measurement and compensation (for IR tests), motor direction of rotation plus supply phase rotation tests.

The MTR105 is powered by six AA alkaline primary cells. As an optional accessory, rechargeable NiMH AA cells can be used with an external power supply and adaptor to charge the batteries whilst in the instrument. Lithium primary (not Lithium Ion) cells can also be used.
