美国NAI 公司全称North Atlantic Industries，即北大西洋工业，其官方简介：
Since 1955, NAI’s vertically integrated design, manufacturing and verification capabilities have been built with the intense focus of an organization that defines every action and investment based on our ability to Accelerate Your Time-to-Mission™. Offering a portfolio of rugged embedded COTS products, including over 70 pre-integrated modules, Multifunction I/O Boards, Single Board Computers (SBCs), Systems, and Power Supplies, NAI has built a reputation for supporting the world’s most demanding defense, commercial aerospace and industrial applications.
基本意思是说，公司成立于1955年，是个老公司，经验很丰富，产品很精专。主要为航空航天等国防领域用户提供产品。
NAI在国内也卖了很多年了，主要是其自整角和旋转变压器，以及LVDT/RVDT的测量仿真产品。这些产品不是说国内做不了，但目前国产的精度和可靠性和NAI的还不能比。国内的很多计量院所，都用NAI的产品作为参考，可见其技术水平。要说缺点，只有一个，就是贵。
