CP4430C

Document the measurement accuracy of your Ayríís with reliable calibration measurements using the CP4430C calibration set. The set includes a spherical contact angle standard with precisely defined sphere radius, a stand for correct placement of the Ayríís, and a certificate attesting to the accuracy of the standard. The exact surface curvature of the sphere simulates a perfectly round drop with a defined, virtual contact angle. The result for the radius is used to determine the measured value deviation.
