Megger MTR105 Rotating Machine Tester
The Megger MTR105 is a versatile, handheld rotating machine tester designed for comprehensive diagnostics of small to medium-sized motors (up to 500 HP). It integrates multiple testing functions—including insulation resistance, low resistance, capacitance, inductance, and motor rotation checks—into a single rugged device. With features like temperature-compensated insulation testing, three-phase analysis, and robust data storage, the MTR105 is ideal for maintenance teams, service workshops, and commissioning engineers working in demanding environments.
Description
The Megger MTR105 is a dedicated static motor tester that combines Megger’s proven insulation resistance (IR) testing capabilities with advanced features such as Digital Low Resistance Ohmmeter (DLRO) four-wire Kelvin testing, inductance and capacitance measurements, and motor rotation diagnostics. This all-in-one solution eliminates the need for multiple instruments, streamlining workflows and reducing equipment investment.
Designed for professionals in industries like utilities, manufacturing, HVAC, transportation, and motor maintenance workshops, the MTR105 is particularly beneficial for diagnosing small to medium-sized motors up to 500 HP. Its comprehensive testing capabilities allow for a complete motor assessment, from insulation resistance to winding continuity, in one portable device.
The MTR105 features a full-color graphic display that presents values and trends at a glance, allowing users to validate pass/fail criteria and move decisively to the next task. Its IP54-rated design ensures durability and reliable performance in various field conditions, protecting against moisture and dust. The instrument also includes onboard storage for up to 256 motor results, which can be conveniently downloaded to a USB device for analysis using Megger tools or other software.
