Product Features

Sigma 700 and Sigma 701 are state-of-the-art force tensiometers that are able to perform a wide range of measurements and adapt to a great variety of experimental settings. This versatility makes them suitable for research, development, industrial quality control, and educational use.

Sigma 700

Sigma 700 is a multipurpose tensiometer well suited for dynamic contact angle and wettability measurements of heavy solids and powder samples. It has an auto-calibrating microbalance that measures over a wide range and can take a maximum load of 210 g.

Sigma 701

Sigma 701 is also a multipurpose tensiometer equipped with a different microbalance that measures in a narrower weight range with high sensitivity. It has a maximum load of 5 g. The sensitivity of Sigma 701 makes it optimal for dynamic contact angle measurements of fibers.
