铁谱仪可广泛用于各行业的内燃机、燃气轮机、齿轮箱、轴承、液压系统等大型机器和零部件进行有效的磨损检测，有统计表明，应用铁谱技术所带来的保证重大设备安全运行，减少故障发生，降低维修费用以及在摩擦学和润滑油品质评定研究领域中，取得了显著的经济效益和社会效益。 根据分离磨粒、检测磨粒的不同方法，研制了不同的。铁谱仪主要有三种类型：直读铁谱仪、分析铁谱仪和旋转式铁谱仪。当今，又成功研究了在线式铁谱仪。此外，还有用于收集干粉中铁磁性颗粒的气动式铁谱仪。

Ferrography can be widely used in various industries of the internal combustion engine, gas turbine, gear box, bearing, hydraulic systems and other large machinery and parts wear detection effectively, statistics show that the application of ferrography to ensure the safety of major equipment operation caused by technology, reduce the failure, reduce the maintenance cost and quality evaluation in tribology and lubrication oil in the research field, has achieved remarkable economic and social benefits. Different methods have been developed on the basis of the different methods of separating the abrasive particles and detecting the abrasive particles. There are three main types of Ferrography: direct reading ferrography, analytical Ferrography and rotating ferrography. On the other hand, online ferrography has been successfully studied. In addition, there are also pneumatic ferrography for collecting ferromagnetic particles in dry powder.
