Du Nouy Ring Interfacial Tension Testing Apparatus for Insulating Oil

Du Nouy Ring Interfacial Tension Testing Apparatus for Insulating Oil

Application

This tester is widely used to measure interfacial and surface tension for various liquids and petroleum products such as transformer oil, lube oil, turbine oil, hydraulic oil, etc. The equipment is fully automatic that only pressing the "start" button can finish the tension value calculation according to the input parameters.



 

Main Features

1.Adopts original and fast-response electromagnetic force balance sensor and microprocessor intelligent control to improve measurement accuracy and linearity;

2.Only one calibration point is required, no need of zero adjustment potentiometer and full range potentiometer;

3.Integrated temperature detection circuit and automatic temperature compensation of the test results to avoid the impact of temperature on the tension value;

4.Automatically zeroes, measures, calculates, displays print results, and 300 pieces of measurement results can be stored;
