Viscosity is an important measure of flow performance, and increasingly stringent quality specifications require more and more accurate control of raw materials and intermediate products. Kinematic viscosity is an important characteristic of Newtonian liquids, and the Uhler capillary method based on the principle of gas-supported suspension column is the most accurate method.
Principle of capillary viscosity measurement method: At a certain temperature, the precise measurement of a given volume of Newtonian liquid under the action of gravity through the capillary takes time to calculate the liquid viscosity. Kinematic viscosity calculation formula: V=KT. Among them, stable temperature and accurate timing are the basic conditions for accurate results of viscosity testing.
Manual viscosity test series complete solution viscosity test, no need to patchwork, based on the most concise equipment, unique design, to ensure that the experimental process has a constant, uniform temperature field, get the most accurate viscosity measurement results.
Widely used in polymer materials and pharmaceutical raw materials and other polymeric materials, can be tested to obtain kinematic viscosity, dynamic viscosity, relative viscosity, specific viscosity, viscosity and characteristic viscosity, viscosity average molecular weight and so on.

1. Applicable standards
To meet the needs of Newton liquids (solution lubricants, gasoline, fuel oil, organic and liquid, strongly diluted polymer
solutions), to meet the quality control and development of polymer materials, And fully meet, comply with GB 1632, ISO1628, ASTM D4603, GBT35173-2017, GBT35262-2017, SNT1015-2001, GB/T14190, GB/T17931, GB/T1632 , ISO307, ASTM D789, GB/T12006, HG/T2234, GB/T3401, GB/T12005, GB17514, GB/T28610, HG/T 2758, FZ/T 51008-2014, Pharmacopoeia (can do 3Q Certification) and other relevant international and domestic viscosity test standards.

3. the main performance
1, the host is composed of high precision water tank, flow through the circulation refrigeration and viscosity test necessary accessories such as viscosity tube and viscosity tube fixed support, high precision calibration thermometer (0.01ºC) anso on.
2, suitable for a variety of viscosity tubes: Uzbek viscosity tube (up and down cutting distance 40mm, Strictly in accordance with GB/1632-93, ISO3105, ASTM D446, DIN 51562 and other standards), micro-Uttonite viscosity tube, dilutive Uttonite viscosity tube, micro-Auttonite viscosity tube, Cannon-Fenske viscosity tube, Pinping viscosity tube. Viscosity tube fixed firmly: stainless steel jig type, stainless steel basket type two options.
3, double bin design: high precision constant temperature tank measurement bin and adjustment bin separation design. The hot and cold bath liquid is mixed in the regulating chamber, pumped into the measuring chamber through the cylindrical nozzle, and then transported by the pump to the measuring chamber through the porous drainage pipe, which not only ensures the minimal temperature difference of each measuring position, but also ensures that the liquid level of the measuring chamber remains constant, and is not affected by liquid evaporation, so as to ensure the accuracy of the viscosity results (if the liquid level cannot be maintained constant, when the liquid level drops to a certain height, the viscosity of the liquid level can be reduced to a certain height). The air temperature affects the test temperature, and viscosity is very sensitive to temperature, which will cause a large deviation in viscosity results).
4, nozzle type mixing bath, no stirring. Ensure the stability of the test water surface, convenient for the tester to observe
accurately, and make the temperature distribution more uniform.
5, high power flow type refrigerator: to provide cooling source for constant temperature bath.
6, set white LED lighting belt, to provide stable lighting for the test area. Durable, almost no need to change supplies. The
seamless all-welded #304 mirror stainless steel inner liner provides a clearer view and ensures reliability for easy observation and placement of the measuring table, highlighting the high quality of the high-grade positioning.
7, imported thermostat, imported water pump, stable and reliable quality.
8, imported double-layer transparent tempered insulating glass, large area observation window, easy to monitor the test status.And ensure good thermal insulation effect, reduce the impact of the environment on the temperature field of the measuring tank.
9, pulley mechanism bath cover extraction plate: easy to install viscosity tube and test when switching, reduce bath evaporation and prevent foreign matter from falling into.
10, high and low liquid level automatic alarm, and high temperature cut off protection function, to ensure safety during use.
11. External circulation flow indication.
12, equipped with special water purification agent, greatly reduce the microbial growth rate. Don't bother with frequent water changes.
13, can be easily upgraded to automatic viscosity tester: automatic sampling, automatic constant temperature, automatic
measurement, automatic calculation, automatic cleaning and other functions. Instead of human eye observation, watch and calculation and other manual operations, so that the timing accuracy is better, up to 0.01S, with better parallelism and
repeatability.
14, refrigeration linkage socket: one-button shutdown, refrigeration and thermostat bath need not be switched on and off in order.
