Particle Quantifier Instrument – ToronPQI™ Series
ASTM D8184-Compliant Ferrous Debris Monitoring Solutions
ToronPQI™ Series by Torontech represents a new generation of Particle Quantifier Instruments (PQI) designed for precise, rapid, and reliable determination of ferrous wear debris in lubricating oils, greases, and hydraulic fluids. Conforming fully to ASTM D8184, the ToronPQI™ Series offers standardized and repeatable results for predictive maintenance, oil analysis, and machine condition monitoring.
With three advanced models — ToronPQI™1000, ToronPQI™ 2000, and ToronPQI™ 3000 — this series provides scalable options for laboratory and field applications alike, ensuring consistent PQ (Particle Quantifier) readings and superior diagnostic accuracy.
About ASTM D8184 Standard
ASTM D8184 defines the Standard Test Method for the Determination of Ferrous Wear Debris in Lubricating Oils and Hydraulic Fluids by the Particle Quantifier Method (PQ Method).
This globally recognized standard specifies procedures for measuring the magnetic flux disturbance caused by ferromagnetic particles suspended in lubricating fluids. The resulting PQ Index provides a quantitative measure of ferrous contamination — a key indicator of equipment wear.
By conforming to ASTM D8184, Torontech’s PQI instruments ensure:
- Reliable, traceable, and repeatable PQ measurements
- Sensitivity to a broad particle size range (typically ≥ 1 μm)
- Fast, non-destructive testing with minimal sample preparation
- Standardized reporting for consistent oil analysis across sites
