Harsh operating conditions, extreme load variations and the high-dollar costs involved in equipment replacement make fluid analysis a necessary part of doing business in the mining industry. Routine testing identifies small problems before they become major failures allowing you to meet the demands of your customers on time. Maximize asset reliability and regain control of your production schedules with an effective fluid analysis program with POLARIS Laboratories®.

Diesel Engines

Routinely monitoring a diesel engine oil’s viscosity, as well as its ability to neutralize acids and disperse and suspend soot particles produced during combustion, can indicate whether or not anti-wear additive and dispersant/detergent levels are providing sufficient engine protection.

Gear Systems

The primary objective of a gear oil is to provide a film between moving metal surfaces sufficient enough to prevent wear and the damaging affects of pitting and scuffing. Low levels of sulfur, boron and phosphorous could indicate that wear-reducing additives have been depleted.


A hydraulic fluid’s viscosity should be low enough to minimize friction loss, yet high enough to prevent fluid leakage and provide satisfactory protection against wear. It should have good oxidation stability to prevent sludge from forming, sufficient water separability and air release properties and resistance to foaming.

Coolant Analysis

Coolant Analysis takes the guess work out of properly maintaining a cooling system and can identify maintenance problems before catastrophic engine failure occurs. Regular coolant testing and routine maintenance can help you achieve maximum system efficiency and save you time and money in less downtime, fewer repairs and determining proper drain intervals.
