The measuring principle of this instrument is to vaporize or burn the sample under certain conditions, then burn it in a strong heat source, and calcine the solid residue. Therefore, the ash content of the test product is determined. The instrument is suitable for detecting unused commercial engine coolant and liquid rust inhibitor, and can also be used to identify the type of coolant and rust inhibitor, but it is not suitable for determining the content of total inhibitors.
