Universal Surface Tester GH100
The Universal Surface Tester GH100 allows contact angle on large surfaces of any size to be measured. This is made possible by the innovative measuring optics arrangement that even permits the extensive characterization of very large samples. The measuring head can be used as a mobile unit, a laboratory instrument or together with a robot.
