Contact angle Analysis

CA-1P

The CA-1P provides precise contact angle measurements to quantify surface wettability and ensure rigorous standards for surface treatment and cleanliness.

CONTACT ANGLE ANALYSIS

CA-1P Contact Angle Module for PAT1P

The CA-1P determines the contact angle formed at the intersection of liquid, gas, and solid phases to provide a quantitative measure of surface wettability. By analyzing the drop shape—governed by the three forces of interfacial tension—the instrument delivers precise data on surface characteristics. This makes it an essential tool for evaluating the effectiveness of surface treatments and ensuring strict cleanliness standards in industrial and laboratory environments.
