Measurements International (MI) is a global leader in the design and manufacture of ultra-precise electrical metrology and transformer loss measurement systems. Founded nearly 40 years ago, MI has built a legacy of advancing the science of electrical measurement and supporting the world’s most demanding calibration and testing applications.

What began as a small innovator solving complex metrology challenges has grown into a trusted provider for the majority of National Measurement Institutes (NMIs) and hundreds of primary standards laboratories worldwide, as well as transformer manufacturers across the globe. MI’s solutions underpin critical measurement infrastructure that supports scientific research, energy systems, aerospace, and international trade compliance.

Driven by continuous investment in research and development, MI has introduced industry-leading innovations including high-accuracy self-balancing bridges, temperature-controlled artifact calibrators, and fully automated transformer loss measurement systems. This commitment to innovation, quality, and customer support has established MI as a preferred partner for organizations that require traceable, repeatable, and highly reliable measurement performance.
