Sartorius microwave drying moisture meter LMA200PM takes the oven drying method as a reference, and quickly heats the sample by absorbing microwave radiation through the sample. This experimental method determines the moisture content of the sample by heating the sample and calculating the weight change of the sample before and after heating. Due to the principle of microwave drying-microwave radiation at 2.45GHz only affects the water molecules (that is, strongly polar molecules) in the sample and is not absorbed by other non-polar molecules. In the first stage, the water-in-oil emulsion in the crude oil is demulsified and dehydrated with a small amount of microwave energy (level = 20%); in the second stage, high-power microwave (level = 65%) is used for water drying. Because the weighing system of the moisture meter has an external calibration function, it shows that the measurement result of the moisture meter-moisture content is traceable.
