In accordance with GB/T4029-2008 standards,the series products according to Archimedes principle buoyancy method.it is the new type sodium silicate modulus and density tester that has been researched and produced by Quarrz.density SG,modulus M,baume Bé can be tested accurately and quickly.

Sodium silicate is the common name for compounds with the formula Na2(SiO2)nO. A well known member of this series is sodium metasilicate, Na2SiO3. Also known as waterglass or liquid glass, these materials are available in aqueous solution and in solid form. The pure compositions are colourless or white, but commercial samples are often greenish or blue owing to the presence of iron-containing impurities. The modulus M of sodium silicate is determined by the proportioning of quartz sand and alkaline, i.e. molar ratio of SiO2 and Na2O, modulus that displays the composition of sodium silicate is one of important parameter, and is commonly between 1.5 and 3.5. The larger the modulus is, and the more difficult the solid sodium silicate solves in water. the content of water glass in water solution is indicated by density or baume.Viscosity of water glass is closely related to modulus,concentration and temperature.

Technical Parameter:
(1) AU-300WG modulus resolution:0.1M,baume resolution:0.01Bé ,density resolution:0.001g/cm3
(2)AU-120WG modulus resolution:0.01M,baume resolution:0.001Bé,density resolution:0.0001g/cm3

Features:
1. Density,modulus,baume can be read directly.
2. High precision,simple operation,stability and durability.
3. Dynamic measuring,density value can be updated along with liquid formula.
4. Function of water temperature setting and air buoyancy density compensation setting.
5. Function of buzzer warning and overload warning.
6. Including RS-232C interface.it is convenient to connect PC with printer.AU-40 can be chose to print data.
7. Equiped with special windproof dustproof cover,convenient structure,sturdy and durable.
8. 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 value,modulus,baume 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.

Optional Accessories:
AU-40 printer,AU-20B anti corrosive liquid measurement assembly,AU-20A standard liquid measurement assembly.

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.
