The course of work
When test, product to be measured is placed on weight-scale table waterborne first, product to be measured is measured in sky by force value sensor
Weight value in gas, is calculated as m1；Then product to be measured is placed on weight-scale table under water, and is filled the water into water tank, made to be measured
Product is totally submerged Yu Shuizhong, measures the underwater weight value of product to be measured by force value sensor, is calculated as m2；M1-m2 is
The volume of product to be measured is acquired according to the density of known water with the weight of the isometric water of product to be measured, is existed further according to product to be measured
The ratio between weight value and product volume to be measured in air, obtain the density of product to be measured.
Beneficial effect
