Foaming testing - Foaming can result from excessive agitation, improper fluid levels, air leaks, contamination or cavitation, the pitting or wearing away of a solid surfaces as a result of the collapse of a vapour bubble. Foaming can cause sluggish operation and cavitation in pumps or fluid transfer devices.

  pH Testing - pH is a measure of the coolant's acidity or alkalinity. Whereas a coolant's neautralisation number is related to the quantity of acid - or base-forming materials in a solution, pH indicates their intensity. Coolant pH range should remain between 7.5 and 11 to provide adequate corrosion protection.
• Resistivity Testing - The resistivity of a liquid is a measure of its electrical insulating properties under conditions comparable to those of the test. High resistivity reflects low content of free ions and ion-forming particles and normally indicates a low concentration of conductive contaminants.
• Ferrous Testing - This test identifies any rust within the coolant indicating lack of rust inhibitor.
• Freezing Point Testing - Tests what point the coolant freezes at to ensure it is able to carry to remain fluid in low temperatures.
• Nitrite Testing - Nitrite is an inhibitor for cast iron, steel and liner cavitation protection. Excessive levels can lead to solder corrosion, precipitate formation and water pump failure.

The Ferrous Wear Index gives an indication of the total measure of Iron (regardless of size) in the sample. This technique is used to determine early component wear.
