Predictive Maintenance Services, Inc.

We Provide The Following Services:

Spectrometal Analysis:Used to determine type and quantity (in ppm) of wear, contaminants and additive metals in lubricants, fuels, coolants and greases.

Analytical Ferrography:Determines size, shape and origin of wear and contaminants. Can detect particles over 200 microns in size, wear modes and effects of additive depletion.

Copper Corrosion:Tests for corrosion to yellow metals (copper alloys such as brass or bronze etc.)

Direct Read Ferrography:A quantitative measurement of wear and contamination. Used in trending.

Viscosity:Measures resistance to flow of a lubricant at a given temperature. Can indicate improper oil, oil oxidation, contamination with another fluid or used as a spec test.

Glycol:Detects glycol (antifreeze). Glycol can corrode bearings, plug filters and deposits on wearing surfaces causing catastrophic failure.

Particle Count:Gives the quantity of particles in specific size ranges. Indicates cleanliness levels of a lube. Determines filter efficiency, used as a guideline for warranty evaluation and aids in establishing oil/filter change intervals.

FT-IR:Infra-red analysis detects oxidation and nitration rates. Also detects water, glycol, fuel dilution, soot and sulfation. Can be used as a quality control check to monitor antiwear additive levels.

AN (Formerly TAN):Detects acidic material in a lube which leads to corrosive wear. Usually indicates additive depletion.

BN (Formerly TBN):Determines alkaline reserve of a lubricant which is its ability to neutralize acids. Usually performed on engine oils. Indicates additive depletion.

Pentane Insolubles:Identifies solids and oxidation byproducts in a lubricant. Used primarily in hydraulic, bearings or gear systems.

Toluene Insolubles:Same as Pentane Insolubles but used more often to determine soot levels in diesel engines.

Flash Point:Detects the presence of fuel or solvent which thins the oil and thus reduces its load carrying ability and increases wear.

Fire Point:Determines the point at which an oil will continue to burn once ignited.

Viscosity Index:Shows the effect of temperature change on a fluid.

RPVOT (Formerly RBOT):Measures the oxidation stability of turbine oils.

API Gravity:Physical characteristics of fluids.

Specific Gravity:Physical characteristics of fluids.

Antifreeze Testing:Freeze point, pH, reserve alkalinity, percent water, specific gravity.

Brix:Measurement of dissolved solids.

Karl Fischer:Water testing from parts per million to 100%. Our equipment can also test fluids that normally cause side reactions with Karl Fischer reagents such as engine oils, cutting fluids, tractor hydraulic fluids, etc.

Fuel Testing:Microorganism testing, cleanliness levels, water content, API gravity, cetane index, distillation, cloud point, pour point, cold filter plugging point, sulfur content, oxidationstability, FAME, cold soak, Rancimat, Low Temperature Flow Test, Cetane Number, flash point, viscosity, Copper Corrosion, Ash content and more.
