Abstract

In a method for determination of corrosion protection in a combustion engine coolant, both the coolant's refractive index and its conductivity are measured on a small quantity of coolant taken from the engine. The values thus obtained are used together to arrive at a measure of the corrosion protection of the coolant. Lightweight handheld instruments, namely a refractometer and a conductivity meter respectively, are used for the measurements. These instruments are simple and inexpensive and quickly provide measured values of sufficient accuracy for a quick answer as to whether the corrosion protection of the coolant does or does not meet specified requirements to be achievable by means of tables, diagrams or by simple formulae or by putting these into a computer.
