Megger MTR105 Best Rotating Machine Tester
Introduction of Megger MTR105
The Megger MTR105 is a specialized static motor tester, combining Megger’s trusted and reliable Insulation Resistance (IR) testing with the classic features and dependability that Megger is known for. This versatile motor tester builds on Megger’s proven infrared testing technology by incorporating DLRO four-wire Kelvin low resistance testing, along with inductance and capacitance measurements, all within a rugged handheld device—a first of its kind.
Additionally, the MTR105 offers temperature measurement and compensation for infrared testing, motor rotation direction, and power phase rotation testing. These enhanced capabilities make the MTR105 a highly versatile, portable motor testing tool for real-world applications. It features a robust outer shell for added durability, earning an IP54 weatherproof rating for enhanced protection in challenging environments.
