TEN302 Interface, surface Tensiometer (Du nouy Ring / Wilhelmy Plate method)

TEN301, TEN302 Interface/surface tensiometer adopt the Wilhelmy plate /Du Nouy ring method. Precision electronic analysis balances with high measurement accuracy are built in. The integrated control is carried out by the industrial control machine, the sampling is more accurate, the frequency is higher, and the repeatability error is less. Lifting platform using ball screw transmission, transmission is stable, step-in motor control speed adjustable, drive distance more accurate. WinCE interface, can work for a long time, fully automated data analysis to further reduce errors, one-click fully automatic whole process measurement, the results of automatic calculation display, results can be saved, historical reports readable. The instrument can be used for liquid measurement with medium and high viscosity, and achieves surface tension testing in ink, paint, petroleum and other industries.
