AU-300API Petroleum Hydrometer , Petroleum Densitometer , Petroleum Testing Equipment


The series products according to Archimedes is the new type density and API tester that has been researched and produced by Quarrz.density,API can be displayed automatically.Function of accuracy,quick measuring,convenient,reliability.In accordance with ASTM D1298 is suitable for petroleum and energy industry.


Technical Data:
(1) API° and specific gravity have the nonlinearity inverse relation.High specific gravity liquid will show lower API°.
(2)Every tonne barrelage of raw petroleum can be calculated according to API°.
(3)Specific gravity and w/gal has the linear relation.
(4)Raw petroleum can be classify as light crude > 31.1 API°;middle distillate is between 22.3 API°~31.1 API°,overweight crude < 10.0 API°

Technical Parameter:
AU-300API density resolution:0.001g/cm3,API resolution:0.1°API,concentration resolution:0.1%
AU-120API density resolution:0.0001g/cm3,API resolution:0.01°API,concentration resolution:0.01%


  • Any kinds of petroleum liquids can be measured.
  • density,API can be read directly.
  • High precision,simple operation,stability and durability.
  • Dynamic measuring,density value can be updated along with liquid formula.
  • Function of water temperature setting and air buoyancy density compensation setting.
  • Function of buzzer warning and overload warning.
  • Including RS-232C is convenient to connect PC with printer.AU-40 can be chose to print data.
  • Equiped with special windproof dustproof cover,convenient structure,sturdy and durable.
  • Volatile liquid,corrosive liquid,viscous liquid,strong acid and strong base liquid can be measured quickly(relative accessories is available)

Measuring Procedure:
(1)Place beaker filled with sample on testing board.and deduct weight of pothhook.
(2)Make standard weight hanged on the pothpook and submerged into liquid to be tested.Density,API,concentration will be displayed.


Standard Accessories:
host,measurement plate,AU-20A standard liquid measurement
assembly.tweezer,thermometer,100g weight,windproof dustproof cover,measurement
support,power transformer.

AU-20A standard liquid measurement assembly:
two pcs of stainless steel pothpooks,two pcs of normal glass weight,one pcs of standard stainless steel weight,two pcs of beakers.

Anti-counterfeiting Announcement:

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 machine.
  • Method three:Check security code that generate automatically by machine number.
