What instrument can be used to measure kinematic viscosity?


The kinematic viscosity is the viscosity of the fluid and the same temperature of the fluid density ratio. The unit is (m^2) /s. Use the lower case letter v.
There are three methods for determination of viscosity, kinetic viscosity, kinematic viscosity and conditional viscosity.

Dynamic viscosity: ETA t two liquid layer is 1 cm apart; the area was 1 (CM) relative speed of 1 cm / sec generated resistance units for g / cm / sec. 1 g / cm sec =1: general industrial dynamic viscosity unit expressed by poise.

Kinematic viscosity: when the temperature is t degrees centigrade, the kinematic viscosity is indicated by the sign gamma. Kinematic viscosity is widely used in the determination of jet fuel oil, diesel oil, lubricating oil and other liquid petroleum products, petroleum products after use of lubricating oil, crude oil viscosity, viscosity was determined by capillary viscometer method.


IVS300 Viscometer
 Hangzhou Zhongwang Technology Co.,LTD designed the automatic test instrument IVS300 based on ISO1628/ ASTM D 2857. This machine was widely used in polyester (PET), quality control and testing of raw materials, nylon, silicone polymers such as polyacrylamide industry, containing all the viscosity of the formula can be obtained directly by viscosity, viscosity, relative viscosity, characteristic viscosity and viscosity average molecular weight of the.


In the kinematic viscosity automatic tester IVS300 system uses the modular design, mainly by the viscosity measurement unit, precision constant temperature bath, through the cooler and the main controller and the viscosity of special software modules;



Automatic Viscometer Measuring Unit
Each measuring unit is an independent system, and all test procedures are completed by each test head. The test unit and the main controller are connected only through one data line;
The pressure method is adopted to lift the sample; the loading and unloading of the viscosity tube adopts a unique pressing block mode;
The pump pressure can be automatically adjusted by software according to the viscosity of the sample;
The measuring fiber is made of stainless steel smart fiber, which can automatically change the intensity of the fiber because of the different colors of the sample; 
The viscosity thermostat is designed and the measuring zone isolation constant temperature zone, will affect the temperature of the bath temperature in the process of fluctuation on the measurement is reduced to the minimum, to ensure a constant level measurement of temperature field and temperature region;

Constant Water Bath




Viscosity constant temperature tank has high and low water alarm function. The inner tank is made of mirror stainless steel, large double toughened hollow glass observation window and LED lighting;
Cooler adopts the most advanced PTL refrigeration technology, continuous operation life of more than 50 thousand hours.







IVS300 Software 
Hangzhou Zhongwang Technology Co.,ltd Software is very powerful, with all sectors of the different viscosity formula, including the Bill Meyer formula / Hagen Poiseuille formula / formula / Hagens Mark Houwink formula / Martin / Solomon - Xiuta formula formula. Customers can be automatically calculated according to needs; Chinese menu; unattended after starting, automatic continuous testing, until the finish of the test data; intelligent identification, such as measurement data does not match the user requirements with buce function; software with rights management, protection of important data will not be free to modify the instrument;

Technical parameter

1. Bath temperature fluctuation uniformity: + 0.01
2. Bath control temperature range: 5-55 DEG C
3. Ting accuracy: 0.01S
4. Measuring viscosity range: 0.35-5000 mm2/s (specific range of use and supporting viscosity tube related)

5. Time measurement range: 0... 9999.99S
