goniometerThe OCA 15 is the entry level measuring device for professional contact angle measurements and drop shape analysis. This device has automatic dosing system which let to obtain precisse and repetative measurements. Measuring range is 0-180° / ±0.1°. Moreover, this device let to conduct measurements using 5 different techniques. Due to possibility of free syringe/ liquid changing surface energy can be measured. Softwere let to calculate surface energy with accuracy ca.   0.01  - 2000 mN/m /± 0.01 mN/m, using various matematical models.
