The ET5678 Coolant Conductivity Tester is a compact, easy-to-use tool designed to quickly assess the electrical conductivity of coolant.

Many EV / hybrid vehicles use a special antifreeze that is not diluted and is manufactured to have very low conductivity. This tester allows users to check conductivity, to ensure that the coolant has not been diluted with water, which is a major safety issue.
