I have an application similar to Wear Debris Analisys
However I'm not form the field and struggle to find the manufacturers of such equipment.
I need to regularly measure steel particles in a fluid.
I got the Trevor Hunt "Handbook of wear debris analisys", but most of the devices he cites are out of production!
If anyone can help, I'm looking for manufacturers/vendors/researchers of Ferrographs and Magnetic particle sensors.
Otherwise I have to build it myself (a lot of work and bad results)
