Rotating TensioMeter

The rotating Tensiometer calculates surface tension by measuring the torque required to detach a platinum ring from a liquid surface. It is used for testing the spreadability of coatings and inks, analyzing the wettability of paper and plastics, and is commonly employed in laboratories for production quality control.
Selection
When selecting, consider that the measurement range should cover the sample's tension values, the precision should match the detection requirements, and calibration certificates should ensure the accuracy of measurements. The platinum ring material is corrosion-resistant, the automatic lifting function reduces human error, and the supporting software supports data export. For samples with higher viscosity, confirm the instrument's torque capacity.
