Automatic instrument for determining the apparent density (porosity) of raw ceramic tiles, mod. DDA/2 (without mercury)

As the porosity of raw pressed pieces depends on the chemical and physical features of the granulate,its distribution and humidity, as well as the pressing power applied, it is extremely important to know thisparameter in order to determine the other variables that contribute towards forming the finished product (raw and fired mechanical strength, shrinkage, etc.). This device is suitable to determine the apparent density of the tested sample by double weighing in air and hydrostatic mode. To execute this test it is necessary to use a special liquid with features of slow absorption that allows to weigh the sample before that the measure might be influenced from the absorption of the same.
