Measurement parameters

Eight key indicators of oil health

The PLUS monitors the parameters that matter most for predictive maintenance and condition-based oil change decisions — application-configured prior to delivery.

💧

Water / Moisture

Early detection of water ingress before emulsification or corrosion damage occurs.

⚖

Viscosity

Continuous kinematic viscosity measurement detects thinning, thickening, and shear degradation.

⚡

Oxidation

Quantifies oxidative degradation of the base oil, a primary indicator of remaining useful life.

🧪

TAN / TBN

Total Acid / Base Number monitoring for engine and industrial lubricant degradation assessment.

📄

Sulphation

Detects sulphation byproducts in engine oils, particularly relevant for diesel and gas engine applications.

⬤

Soot / Carbon

Measures soot loading in diesel and gas engine lubricants to prevent accelerated wear and filter blockage.

⛽

Fuel Dilution

Detects fuel contamination of engine oil — a leading indicator of injector faults or piston ring wear.

🛡

Antioxidants

Tracks depletion of antioxidant additive packages, enabling condition-based oil change decisions.

Applications

Proven across critical industrial assets

The PLUS is deployed on a wide range of rotating and reciprocating machinery where continuous oil condition data reduces unplanned downtime and optimises maintenance intervals.
