Versatile Functions for Precise Tension Measurements

The Force Tensiometer provides a modern and reliable method for the precise determination of surface wetting. By measuring the tensile force generated when immersing a ring or plate, the device delivers accurate results. Two well-established methods are available for determining surface and interfacial tension between two media: the Du-Noüy ring method and the Wilhelmy plate method.

The digitally controlled Sigma 200 Tensiometer performs these measurements fully automatically. With a single button press, the process starts, ensuring a fast and straightforward operation. This user-friendly design not only saves time but also ensures precise and reproducible results. In addition to tension measurements, the Tensiometer allows for the measurement of liquid density, further enhancing its versatility.

Comfortable Data Collection and Precise Quality Analysis

The Tensiometer operates as a standalone device, equipped with a motorized table that enables highly precise positioning of the sample vessel. During measurement, the Du-Noüy ring immerses in the sample, and the device captures the forces generated. The motorized sample table gradually moves downward, measuring the forces directly on the ring or plate lamella. The integrated display immediately shows the measurement values, enabling quick, straightforward data interpretation.

One particularly valuable feature of the digital Tensiometer is its capability to analyze the interfacial tension between oil and water. The ring method provides early indications of the oil aging process, which plays a key role in quality monitoring. ASTM Standard D971-99 2012 describes and standardizes this method for interfacial tension measurement. This makes the digital Tensiometer an essential instrument for quality control in numerous industries. In the chemical and food industries, it meets the highest standards of accuracy, speed, and efficiency, ensuring continuous quality assurance.
