XIATECH testing center provides an extensive breadth of testing services of thermophysical property measurements, including the transport properties and thermodynamic properties. Transport properties of fluids, such as thermal conductivity, heat capacity, viscosity, are the basic information on the designing of heat transfer vessel, and the researches on heat transfer mechanism and efficiency.
XIATECH testing center equipped with professional laboratory staffs and measurement devices, provides accurate viscosity data of liquids in the temperature range from -30 ¡æ to 120 ¡æ and pressure range from 0.1 to 20 MPa. For other temperature and pressure requirement, the user can also consult our senior technical staff.

Test Sample
Almost all kinds of pure and mixture fluids, particularly volatile liquids and high pressure measurement:
Refrigerant: R134a, R12, R22, R123, dimethyl ether and etc.;
Oil: thermal oil, gasoline, kerosene, diesel oil, lubricating oil, compressor oil, refrigeration oil, silicone oil, etc.;
Nanofluids: Alumina nanofluids, graphite nanofluids, Fe3O4 nanofluids, ZrO2 nano-fluids;
Chemicals: water, toluene, alcohols, ionic liquids, salt solutions, etc.;
Application(Viscosity measurement of mixture)
The viscosity of mixture of oil and refrigerant is very important in the refrigerant cycle system.
The viscosity of mixture of frozen oil / R134a in the pressure range from 0.1 to 2.5MPa at temperature of 40¡æ were measured by VM 4000 and pressure control module . Experimental results are showed in Figure 1, from which it can see that the viscosity increases as the temperature increased.
