Model No: HO-IAD-CAM-01

Holmarc’s Contact angle meter Model no: HO-IAD-CAM-01 is a basic educational equipment for illustrating the basics of contact angle measurement to students. It has manual dispensing with CCD interface for measuring contact angle of liquids on solid surfaces. The surface over which contact angle is to be measured is held in horizontal position to find out contact angle using sessile drop method. The equipment enables:
Static Contact angle measurement
The instrument uses sessile drop method which is the standard method for quick and accurate wetting results for finding out Contact angles.

State-of-the-art optics, precise opto-mechanics, high-resolution CCD detector and associated electronics used in our instrument guarantee error free measurements. Manual dosing of liquids can be done using this equipment.
