(1) All kinds of liquid can be measured instantly without limitation.

(2) High precision measurement,easy operation,stable and durable.

(3) Change the liquid formula during dynamic measuring,density value updated accordingly.

(4)AU-300LM,AU-120LM can display density value,baume degree,concentration,sugar degree, plato degree.

(5)The density of samples with the temperature from normal to 100 ºC can be measured.

(6)Take samples conveniently,and 50CC or even less would be ok.

(7)There is no cumbersome debugging and operation compared with traditional wechsler balance method and pycnometer method.

(8)The specific gravity of liquid with required temperature can be measured by coordinating operation with constant temperature sink.

(9)It is very easy to clean measurement cup,and isn't limited by the size of pycnometer caliber.the cup would be reusable and worked with other cups.

(10)volatile liquid,corrosive liquid,and viscous liquid can be quick measured(choose relevant accessories)

(11) Including output RS-232 interface;It's convenient to connect PC and printer.AU-40 could be optionally availabe to print result.

(12)Adopt the completed special wind dust cover.which makes the combination convenient and durable.


Measurement 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 value would 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.

 

Optional Accessories:

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.

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】along with flickering constantly.place 100g weights onto the centre of measuring bridge.the machine will do calibration automatically.when screen display 【END】firstly,then display【100.000】.it indicate the calibration is done.

(4)Take down the weights,the machine will return to measuring mode automatically and display 【0.000】.

 

How to do water 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 4℃ of water.As for water temperature compensation coefficient,this instrument was stored of memory value for 0~49℃.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 6℃).Default temperature of this machine is 25℃.Temperature value and other value would be revised by long-press 【A】Key.Here below is detail procedure.

(1) Long-press 【A】till screen display 【C25】

(2) Press 【A】to revise numbers.Press 【ZERO】to shift

(3) Press 【ENTER】to confirm after revise,then get back to measuring mode.
