How can I practically measuring the thickness and density of frost that growth over plate surface?

05 October 2020 1 4K Report

My new research dealing with frost growth over cooled surface of flat plate using cooled water vapor, and I need to measuring practically each of frost thickness through the growth also I need to measuring accurate value of density. Experimental work consist from small acrylic room (30*20*20 cm^3), where the cooled surface ( 10*10*0.2cm^3)inside the test space.

With my respect

Claude-Alain Roulet

The density can be calculated from thickness and weight. So weigh the plate before and during frost deposit. If the ice is compact, the thickness can be measured with a palmer. If not (e.g. snow), the thickness of its shadow obtained with light parallel to the plane surface can be measured.
