The FerroCheck 2000 series of portable magnetometers is designed to quickly and conveniently measure total ferrous wear particulates in lubricating fluids. The FerroCheck 2000 unit, which measures ferrous wear particles in oils, is now joined by the FerroCheck 2100 version that adds the capability to quantify up to 15% ferrous debris in grease. The instruments can help users accurately gauge evidence of ferrous wear and use the data to support condition-based maintenance programs for engines and machinery in fleet and industrial applications.
