T2FM Q500 – Laboratory Ferrography for Wear Particle Analysis
Laboratory Ferrography provides detailed examination of wear and contaminant particles suspended in lubricating oils and other operating fluids. Rather than only measuring the amount of debris present, ferrography allows analysts to study particle size, shape, composition and distribution to better understand the type of wear occurring inside machinery.
The T2FM Q500 combines ferrogram preparation oil analysis, bichromatic microscopy, digital imaging and image-management capabilities within one analytical setup. It can be used with lubricant oils, hydraulic fluids, coolants and fuels, giving maintenance laboratories a visual method for investigating abnormal wear and contamination.
During ferrogram preparation, particles are separated from the fluid and deposited onto the ferrogram surface without deformation. The system can separate particles up to 800 µm, preserving morphology that can be important when identifying cutting wear, sliding wear, fatigue particles or contaminants.
Dutco Tennant supplies Laboratory Ferrography solutions for condition-monitoring laboratories, maintenance departments and reliability programmes requiring detailed wear-debris investigation beyond routine particle counting.
Controlled Separation for Detailed Wear Debris Examination
- Complete Sample Delivery – The sample is transferred directly to the ferrogram, helping retain the particles present in the fluid sample.
- Particles up to 800 µm – Large wear and contaminant particles can be separated for microscopic examination.
- Minimal Particle Distortion – The deposition method preserves particle morphology for more meaningful visual interpretation.
- Rapid Ferrogram Preparation – The system reduces delays associated with sample transport through unnecessary tubing before deposition.
- Clear Final Rinse – Controlled rinsing reduces oil residues and halos that could interfere with microscopic viewing.
- Wear Pattern Evaluation – Particle distribution across the ferrogram provides information about severity and type of machine wear.
Bichromatic Microscopy for Easier Particle Classification
- Reflected Red Light – Metallic particles reflect the illumination and appear bright red during examination.
- Transmitted Green Light – Non-metallic particles transmit light and appear green, helping distinguish different debris types.
- Top & Bottom Illumination – The ferrogram can be illuminated from above and below for clearer particle characterization.
- Morphology Assessment – Analysts can examine particle shape, edge characteristics, surface texture and relative size.
- Digital Image Capture – A camera transfers microscope images to a computer for viewing and documentation.
- Historical Comparison – New ferrograms can be compared with earlier samples to identify changes in machine wear behaviour.

Standout Features & Benefits
Goes Beyond Basic Particle Counting
- A conventional Particle Analyzer may indicate particle quantity or size distribution, while ferrography provides visual information about particle morphology.
- Analysts can distinguish between different types of wear debris and contaminants.
- This additional information helps support investigation into the mechanism behind abnormal machine wear.
Preserves Diagnostic Particle Features
- Particles are deposited without significant deformation.
- Shape, edges and surface characteristics remain available for microscopic examination.
- Preserved morphology improves the value of the ferrogram during root-cause investigation.
Visual Separation of Metallic & Non-Metallic Debris
- Bichromatic lighting makes different particle groups easier to recognise.
- Metallic particles appear differently from non-metallic material.
- This helps analysts distinguish wear metals from external contaminants or other debris.
Supports Wear Trend Investigation
- Stored images allow comparison of ferrograms collected at different times.
- Changes in particle quantity, size and morphology can indicate progression of a wear condition.
- Historical comparison provides additional context when investigating developing machine problems.
Recognised Analytical Methodology
- Supports ASTM D7684 guidance for microscopic characterization of particles from in-service lubricants.
