Porosity or void fraction is a measure of the void (i.e., "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0 and 100%.It can be calculated from the extra increased weight through dipping process.this instrument has been researched and developed by Quarrz;Adopt the high precision weighting sensor;Porosity can be read automatically;it has changed the manual computation method;save time,quick,convenient;function of testing density.
AU-120VP,AU-200VP density resolution:0.0001g/cm3,porosity resolution:0.01%

Specific gravity of water would be changed along with water temperature,there is necessary to do temperature compensation in base with specific gravity 1.0000 at 4ºC of water.As for water temperature compensation coefficient,this instrument was stored of memory value for 0~49ºC.Using thermometer to get actual temperature before testing,then revise the temperature to the one shows up in thermometer.(specific gravity would differ 0.001 if the difference between water temperature is 6ºC).Default temperature of this machine is 25ºC.Temperature value and other value would be revised by long-press AKey.Here below is detail procedure.
(1) Long-press Atill screen display C25
(2) Press Ato revise numbers.Press ZEROto shift
(3) Press ENTERto confirm after revise,then get back to measuring mode.
