Thistle tube ferrospectrometer PJ500

Part Number: PJ500

The PJ500 is a portable, thistle‑tube based ferrographic analyzer designed to separate and evaluate wear and contaminant particles in lubricating oil, hydraulic fluids, coolants, or fuels. Meeting ASTM D7690, D7684, and SH/T 0573‑1993 standards, it deposits ferromagnetic particles onto a glass slide by gravity flow—preserving particle morphology and preventing damage from pumps. Ideal for field and lab use, the system ensures reliable wear particle analysis across various industries.

                                                
                                                    Gravity‑Driven Sample Flow                                                
                                            
                                                Oil flows at ~0.4 mL/min through a thistle tube, avoiding pump-induced damage and preserving particle integrity.

                                                
                                                    High-Gradient Magnetic Field
