MachineApplication:industrial ceramic,accuracy ceramci,penetrable sintering metal materials,powder metallurgy,magnetic materials,coal and rock,polymer porosity materials,new materials researching laboratory.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.Measuring Density:AU-120VP,AU-200VP density resolution:0.0001g/cm3,porosity resolution:0.01%AU-300VP,AU-600VP,AU-900VP,AU-1200VPdensity resolution:0.001g/cm3,porosity resolution:0.1%Function and Feature:Easy operation,accuracy,reliability.Any shape can be measured instantly,suitable for quick measurement situation.such as site and laboratory.Either water or other liquid can be used as medium..Dipping liquid density can be set personally.Adopt completed testing board and unobstructed without lifting lid design,more simpler operation,also makes the measuring result more reliable.Adopt completed injection moulding transparent PC water tank(length 15.3cm x width 10.7cm x 9.3cm),which can resist wear,fall off,and corrosion.Equiped special windproof dustproof cover,which makes the structure more convenient and durable.Including RS - 232C communication interface.it is convenient to connect PC with printer.DE-40 can be chose to print measuring data.Gross weight/Size:4.5kg/length 42.5cm x width 17.5cm x height 32.5cmPower supply:AC 100V-240V 50HZ/60HZ Europe standard.Porosity Measuring Procedure:Place sample on testing board to measure weight in air.press ENTER key to memory.After did containing saturated processing,place sample on testing to measure weight.press ENTER key to memory.Place sample into water to measure weight in water.press ENTER key.porosity will be displayed.Standard

intermingled on market today.Most customers had suffered a lot from the brand replacement products,shell brand products,simulation products,and transferring after-sale service products.To protect your rights,please identify seriously when choose goods.Following is the method to distinguish QUARRZ brand product.Method one:Start up,machine will display in sequence:brand,model(such as QUARRZ,AU-300S)Method two:After starting up,press ZERO button and B button at the same time,the machine will display in sequence:brand:model,factory number.of which information correspond to the one marked on machine.Method three:Check security code that generate automatically by machine number.Technical

temperature compensation: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.Packaging & Shipping:Certifications:Our Services:100% Competitive price we are the original manufacturer of densimeter for years, the large scale production make our products
