5-10 Microwave Heat Distribution - Heat Evenness

The microwave heat distribution can be checked indirectly by measuring the water temperature rise at certain positions in the oven:

1.Prepare five beakers made of 'Pyrex', having 100 milliliters capacity each.

2.Measure exactly 100milliliters off water load with a measuring cylinder, and pour into each beaker.

3.Measure the temperature of each water load. (Readings shall be taken to the first place of decimals.)

4.Put each beaker in place on the cooking tray as illustrated in figure below. Start heating.

5.After heating for 2 minutes, measure the water temperature in each beaker.

6.Microwave heat distribution rate can be calculated as follows:

The result should exceed 65%.
