美國磁性分析公司(Magnetic Analysis Coporation) ??
從1928年開始，MAC（Magnetic Analysis Corporation）就是無損檢測領域的先驅。我們運用電磁原理開發首個美國制造的無損檢測系統，用于檢測鋼產品中的缺陷。自此，MAC開始壯大，成為為檢測金屬材料而提供NDT設備和服務的主要來源。
主要從事渦流、電磁、漏磁、超聲檢測設備的生產（棒、管、線、板材渦流、漏磁、超聲在線檢測系統）,在上海設有代表處

Magnetic Analysis Corporation has over eighty years experience as a leader in non-destructive testing. The company developed the first American made system using electromagnetic principles for the detection of flaws in steel products. Since then, MAC has grown to become a major source of NDT services and eddy current, electromagnetic, flux leakage and ultrasonic inspection systems for testing metals worldwide.


Dedicated to a production oriented approach to testing, MAC offers both individual instruments and complete systems that incorporate materials handling and controls as well as non-destructive testing. MAC's focus on the client's concern for reliability and simplicity of design, with minimal need for operator supervision, has evolved from the company's years of in-plant experience.


The results may be seen in plants throughout the world where wire, tubing, bars and metal parts roll through automatic inspection systems without missing a beat. With MAC field engineers and experienced representatives located throughout the United States, and in Europe, Eastern Europe, Turkey, Russian, Brazil, Chile, China, India, Korea and Australia, MAC's commitment to service rates second to none.


Backing up this field staff are some of the top specialists in each area of technology, based in MAC's ISO 9001-2008 certified manufacturing and engineering facility in Mt. Vernon, New York; ISO/IEC 17025:2005 laboratory certified plant in Boardman, Ohio; and M A Nordic's manufacturing plant in ?stersund, Sweden.

MAC instruments and systems are designed to meet the individual needs of customers. Engineers work to define the best test system to meet the customer's specifications and expert technical assistance is provided during installation to ensure superior performance. Maintenance service can be provided for most systems by a service contract, or on a per call basis.

MAC testers and service are also offered at minimum cost and risk through the company's unique leasing program, which includes both equipment and service in one package.

MAC FOUNDED IN 1928

Magnetic Analysis Corporation was founded in 1928 in Long Island City, NY, USA, by William Gould and William Gould Jr. to develop a group of patents for nondestructive electromagnetic testing of steel bars. At the time, most inspection consisted of "sampling" techniques which essentially destroyed part of the bar in the process. A test that allowed use of the product after testing was a very attractive and successful idea.
