The goniometer is one of the best ways to measure contact angle to understand the quality of a surface prior to bonding, or any other adhesion-critical process.
But, your manufacturing surface quality problems aren’t happening in a lab, so why measure them there?
You need a highly accurate, proven, and reliable way to measure surface quality on your material surface, but goniometers are limited by:
Use in a lab setting where minimal environmental variables exist, unlike the manufacturing floor
Profile-view measurement provides only 2 data points on the drop, allowing for incomplete and subjective measurements on non-round droplets
Unable to measure on rough, curved, or vertical surfaces
Requires significant user training and experience
Difficult to measure very low contact angles due to undefined horizon line
We took water contact angle measurement, and made it fully mobile and self-contained so measurements are:
Can be taken in any environment, factory floor or the lab itself
Measurements are nondestructive to the part being tested
Measurement can be made on almost any material, in any orientation and on complex geometries
Provides an accurate and quantitative measurement for reliable testing
We get that a lot… but want to hear why.
