DCA
Tensiometro digitale per la misura della tensione superficiale dei liquidi ( metodo Wilhelmy )
Surface tension and contact angle
The digital tensiometer allows you to determine the static measurement of the surface tension of liquids through the Wilhelmy plate or Du Noüy ring method, combining precision, ease of use and robustness. The TSD tensiometer consists of a precision balance and a fast and accurate sample management system.
It is the right solution to perform quality control analysis or research and development
FEATURES
Practical & Versatile
The DCA tensiometer is equipped with a precision balance and a practical display to set all functions:
| Range | Accuracy | Repeatability | |
|---|---|---|---|
| Surface / interfacial tension | 1 ÷ 1000 mN / m | 0.02 mN / m (dyne / cm) | |
| Contact angle | 1 ÷ 180 degrees | ||
| Density | 0.5 ÷ 2.25 g / cm3 | 0.00005 g / cm3 | 0.00005 g / cm3 |
| Temperature | 0 ÷ 50 ° C | 0.05 ° C | Readability: 0.1 ° C |
Using the temperature probe, it is possible to carry out measurements according to the temperature in a range between 10 and 30 ° C
AUTOMATIC
DCA400
The DCA400 automatic tensiometer performs the measurements automatically and independently of the operator's manual skills. It is equipped with a motorized elevator which move the position of the sample from 0 to 15 nm and the speed from 0.004 to 21 mm / s. This allows to improve the accuracy of the measurement. The movement of the elevator is regulated by software that stores the data relating to each test such as voltage, speed, position and displays the test times based on speed and displacements. DCA400 ensures quality according to the recommendations of the standard GLP (Good Laboratory Practice)
APPLICATIONS
