PQL Ferromagnetic Wear Analyzer PQ300（PQ300B）

Part Number: PQ300B
The PQ300 (portable) and PQ300B (battery-powered) are electromagnetic ferromagnetic wear analyzers designed for rapid detection of ferrous wear particles in lubricating oils, hydraulic fluids, and greases. They use a sensitive coil sensor that measures magnetic field perturbations caused by ferromagnetic particles (>1 µm), automatically providing a wear index (PQ) in just 7 seconds, without sample preparation. The compact instrument supports on-site wear monitoring, helping maintenance teams assess machine health quickly and accurately.
Rapid Measurement
Complete wear index determination in 7 seconds with just a direct oil sample—no pre-treatment needed.
High Sensitivity
Detects ferrous particles >1 µm with 1 PQ resolution and accuracy ±4 PQ or ±1%.
Portable Operation
PQ300 uses AC adapter; PQ300B includes built-in 12,000 mAh battery. Both have a 7″ touchscreen and weigh ~4.7–5.1 kg.
Data Management
USB port and optional PC software allow data upload, trend logging, and report printing.
easy-to-use Interface
Multi-language GUI (Chinese/English) with user-defined naming and straightforward operation.
