Air Densitometer with Display is designed with built-in software to give a direct readout of the density. The Air Densitometer is provided with a density kit which facilitates taking weight in air and weight in water. The Air Densitometer calculates the density and gives a direct readout on the light emitting diode based display. The Air Densitometer with Display enables to check density index by checking two samples from the same batch, one solidified under atmospheric pressure and the other under vacuum.
