Your Leading Ferrogram Maker Manufacturer in China
As a leading manufacturer of ferrogram makers in China, Soohow has over six years of experience in ferrography analysis, with a product line covering analytical ferrogram makers, rotating ferrogram makers, and thistle tube ferrogram makers. Among them, the PA series analytical ferrogram maker and the RF500 rotary particle depositor both support dual-channel simultaneous spectral preparation. All ferrogram makers are equipped with automatic sample introduction and automatic cleaning functions, allowing you to handle other tasks simultaneously while preparing ferrogram slides, significantly improving detection efficiency. During the spectral preparation process, ferromagnetic wear particles are strictly arranged according to their magnetization coefficient and size, with minimal accumulation, providing clear and reliable ferrogram slides for your subsequent microscopic analysis. Our products have been stably applied in dozens of industry-leading enterprises such as Shanghai Baosteel, China National Petroleum Corporation, China National Offshore Oil Corporation, and FAW Group, widely covering fields such as aviation, power, steel, and shipbuilding, providing professional support for predictive maintenance of equipment.

A Variety of Ferrogram Makers for You
Ferrograph makers are widely used in equipment maintenance in industries such as mining, power, steel, and aviation. They help engineers detect potential wear problems before serious equipment failures occur, allowing for preventative maintenance, avoiding unplanned downtime, and significantly reducing maintenance costs.

PA300 Ferrogram MakerCombined into a single 10.1-inch touchscreen, operation is now much easier.
RF500 Rotary Particle DepositorDesigned in accordance with NB/T 51068-2017 standard, it is suitable for industries such as coal mining and petroleum.
PJ500 Laboratory FerrographyIt can effectively prevent damage such as breakage and deformation of abrasive grains caused by external forces during the production of ferrogram slide.
Ferrogram Makers Complementary Solutions
The ferrogram maker can only be used to prepare ferrogram slides. Using biology as an example, a ferrography slide is equivalent to a “microscopic glass slide specimen.” If you want to analyze the abrasive particles on the ferrogram slide, it usually needs to be used in conjunction with other equipment. Soohow can provide you with a complete set of analytical solutions—observing the morphology and measuring the size of abrasive particles on the ferrogram slide using a high-resolution microscope, and then combining it with intelligent abrasive particle analysis software to automatically identify characteristic types such as cutting wear, sliding wear, and fatigue wear, while also allowing direct viewing of the images. By combining the ferrogram maker with other Soohow ferrography analysis equipment, a complete closed loop from sample preparation to wear state identification can be achieved.


Soohow’s Ferrogram Makers Maintain Your Equipment
By observing the morphology, size, and concentration of abrasive grains on the ferrogram slides—the finished product of the ferrogram maker, the location and severity of equipment wear can be determined: cutting abrasive grains, fatigue spalling, and spherical particles; each morphology corresponds to a different cause of wear. This system helps maintenance personnel detect anomalies before malfunctions occur, allowing for early intervention and avoiding production losses caused by sudden downtime.
Timely monitoring of equipment wear means that maintenance can be planned in a timely manner, reducing unplanned downtime, extending equipment lifespan, and thus effectively controlling maintenance costs.
Ferrogram makers are used to separate wear particles from lubricating oil using a strong magnetic field and deposit them onto a glass substrate in an ordered manner according to size to create ferrogram slides. It only performs the ferrogram slide preparation process and does not have analytical capabilities itself; it requires a microscope and intelligent analysis software to observe and diagnose the wear particles.
Regularly collect lubricating oil samples from the equipment, prepare ferrogram slide using a ferrogram maker, and then observe the abrasive grain morphology under a microscope—cutting abrasive grains, fatigue spalling, spherical particles, etc., each correspond to different wear types. Based on the trends in abrasive grain changes, determine the equipment condition and take intervention measures before failure occurs, achieving predictive maintenance.
The ferrogram slide preparation process is simple to operate; after sample injection, the instrument automatically completes the ferrogram slide preparation processs, and ordinary laboratory personnel can learn to use it after a short training period. The real expertise lies in the subsequent particle interpretation and diagnostic steps, which is also the core value of ferrography analysis.
By observing wear particles and detecting abnormal wear early, planned maintenance can be scheduled before serious equipment failures occur, avoiding production losses and high repair costs caused by sudden downtime. At the same time, accurately identifying the location and cause of wear can prevent indiscriminate replacement of parts, reducing spare parts inventory and maintenance costs.
Suitable for any rotating or reciprocating mechanical equipment that uses lubricating oil or hydraulic oil, such as engines, gearboxes, bearings, hydraulic systems, compressors, etc. Primarily used in condition monitoring and predictive maintenance in industries such as aviation, shipbuilding, power, mining, steel, railway, and heavy machinery.
