Goniometer

PG-2 is an automated instrument for measurements of static and dynamic contact angles even on absorbent materials like paper. The built-in camera captures a video sequence of the liquid droplet applied on the surface to measure contact angle (wetting), volume (absorption) and base width (spreading) of the droplet as a function of time. Connects to a standard laptop or PC with a USB port, which will also supply power to the instrument.
FEATURES

• Static Contact Angles: Wetting of non-sorptive surfaces
• ynamic Contact Angles: Wetting, absorption and spreading as a function of time
• Advancing/Receding Angles: Wetting/de-wetting hysteresis of non-sorptive surfaces
• Surface Tension Evaluates.
• The probing liquid from a pendant drop

Contact angle measurement to characterize the interaction between a liquid and a surface.

Complies with test method

• Tappi T458
• ASTM D-724
• ASTM D-5946

Three models are available- PG2, PG3 & PGX+
