Oil Testing Equipment

Fluid Analysis

Lube Oil Analysis

Our Lube Oil Analysis Kit is the ideal tool for getting a detailed understanding on the quality of your lubricant; we test for any wear particles, contamination that could have entered the system and the chemical makeup of your lubricant.

Fluid Testing Information

Moisture Measurement

Traditionally, water in oil has been measured by Karl Fischer titration (a method for determining the moisture content of a sample) and expressed in ppm, which is the total absolute water content, thus not giving any indication whether water is dissolved or free. However, due to differences in oil types and difficulty in predicting aging effects, ppm values are often not sufficient. Therefore, relative values like water activity (aw) in % of saturation are useful parameters for setting alarms in control systems and for monitoring water contents.

Water Content

Most diesel fuels will have some dissolved water content which is normal and harmless. Typically at room temperature this dissolved water content could be around 200ppm (0.02%). As water content increases it can no longer exist as dissolved water and becomes present as free water. The water content becomes critical at concentrations of 0.1% and above.

Oil Composition

Modern lubrication oils are designed to hold a certain amount of water in suspension, when this level is exceeded the water becomes free and separates from the oil, typically new lubrication oils have a value of >500ppm. Bio-degradable oils generally have a higher level of water retention capability. Pure base oils have very limited solubility, which is related to the rations of paraffin, naphthenic, and aromatic compounds. The saturation point at 20°C varies from approximately 30 parts per million (ppm) of paraffin oils to over 200ppm of fully aromatic liquid, but it is typically between 40-80ppm. Solubility may increase significantly with the use of additives. Oxidation products also increase solvating efficiency. Mineral-based transformer oils typically have very little additives and therefore have low solubility like base oil, whereas lubrication oils with greater amounts of additives generally have much higher solubility.
