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
density 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
- 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
- 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
- Power 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.
The bad and good products is 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
- Method three:Check security code that generate automatically by

Tips-How to do weights calibration:
(1) Turn on machine,screen displaying 0.000.press 【ZERO】return zero
if without showing 【0.000】.
(2) In 【0.000】status, Long-press 【ZERO】till shows up 【CAL】.
(3) Which means it is entering into calibration mode.several
seconds later it will automatically show 【100.000】 【200.000】along
with flickering constantly.place 100g,200g weights onto the centre
of measuring bridge.the machine will do calibration
automatically.when screen display 【END】firstly,then
display【100.000】【200.000】.it indicate the calibration is done.
(4) Take down the weights,the machine will return to measuring mode
automatically and display 【0.000】.
