The FerroCheck 2000 Series of portable ferrous analyzers offer accuracy and convenience for total ferrous measurement of in-service lubricating oil and grease. Fast and easy to use samples are analyzed in less than 30 seconds. Small sample volumes of just 1.5 ml of oil or 0.75 ml of grease are needed to measure ferrous content in part per million (ppm) by weight.  The FerroCheck measures the total ferrous content of both small particles from normal machine wear and large abnormal wear particles.

Principle of Operation

The core of the FerroCheck 2000 is a pair of precision rounded coils that when powered, generate magnetic fields. When a small amount of in-service oil is inserted into one of the coils, ferrous particles, such as Iron, Nickel, and Cobalt, interact with the magnetic field and introduce current changes in the coils. The amount of current change is proportional to the amount of Ferrous particles in the oil, calibrated by weight in parts per million (ppm). 

The sample vial that holds the oil or grease sample is designed to optimize the position in the measurement coil. Before the measurement, the coils are automatically balanced electrically, removing the impact on measurement from ambient temperature variation. The result is repeatable and stable measurement regardless of operator and environmental temperature, which is critical for a large service team doing on-site oil and grease analysis in the field.

Combination Kits

FerroCheck 2000 is a great companion device when coupled with other portable oil analysis tools for different applications. Here are a few examples:


Basic Oil Analysis Kit:A quick check with viscosity and ferrous particle concentration in the field is the simplest way to make sure oil is good and machine wear is within alarm limits. The FerroCheck 2000 Series total ferrous particle measurement and the MiniVisc 3050 viscometer combination provides basic oil analysis for field service professionals. 


MiniLab 33 (FluidScan, Viscometer and FerroCheck Combo):Trivector™ MiniLab configuration that tests oil condition (Oxidation, TAN) with the Fluidscan InfraRed Spectrometer, Kinematic viscosity @ 40C, liquid contamination (water) and ferrous content for abnormal wear. It is ideal for small- to medium-sized industrial or power plants looking to start an on-site oil analysis program.
