Key Benefits

3 reasons to invest

Automation at an all-time high

Camera autofocus, ensuring the image to always stay clear, automatic surface mapping, where the sample can be moved into different measurement positions, and automatically generated results with the industry-leading OneAttension software. These are the features bringing automation to a new level for optical tensiometers, simplifying the measurements and increasing accuracy.  

Accuracy and user-independence

With a camera resolution at 5 MP, image quality enhancement with DropletPlus technology, and sensors keeping track of the surrounding environment for good traceability, Theta Flow will provide highly accurate results. The reliable data, in turn, is a key component for user-independent measurements.  

Easy to use with touch display

The touch display improves the user experience making measurement preparation super smooth to handle. Everything from filling the liquids to changing your sample can be done easily at the instrument in seconds.
