美国磁性分析公司(Magnetic Analysis Coporation)   
从1928年开始，MAC（Magnetic Analysis Corporation）就是无损检测领域的先驱。我们运用电磁原理开发首个美国制造的无损检测系统，用于检测钢产品中的缺陷。自此，MAC开始壮大，成为为检测金属材料而提供NDT设备和服务的主要来源。
主要从事涡流、电磁、漏磁、超声检测设备的生产（棒、管、线、板材涡流、漏磁、超声在线检测系统）,在上海设有代表处

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 Östersund, 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.
