Product Description

DT-800 Digital Du Nouy Ring Surface Tensiometer for Liquid Surface Tension Measurement

Introduction:

1. DT-800 Digital Du Nouy Ring Surface Tensiometer for Liquid Surface Tension Measurement adopts the platinum ring method, under non-equilibrium conditions, automatic control using an internal microcomputer, determination of all kinds of liquid surface tension (liquid - gas interface) and mineral oil-water interfacial tension (liquid - liquid interface);
2. After pouring the sample into the sample cup, just press the start button, and the instrument will automatically complete the determination of the sample, and it can automatically calculate the tension value according to the input parameters.
