In the present embodiment, the moisture weight in assumes samples is W=V × d
1, wherein, V is the volume of moisture in sample, and unit is mL, d
1for the density of water in sample, unit g/mL, because sample is immersed in the water weighing completely, so in sample, moisture suffered buoyancy in water is F=V × d
2, wherein, V is the volume of moisture in sample, and unit is mL, d
1for the density of Water in Water Tanks, unit g/mL, because sample cup cup body is porose, and sample cup operates in water tank, and the water in such sample and the water in water tank just reach equalized temperature, i.e. d
1=d
2, therefore, W-F=Vd
1-Vd
2=0, so, when sample in water suspends and weighs, moisture in sample just weightlessness is " 0 ", moisture in sample is when in water, weightlessness is " 0 ", what electronic scale 100 weighed out is exactly the weight of dry in water, utilizes formula to convert and draws dry percent, finally determine percent water rate; Wherein, moisture formula is derived as follows:
