See System E Advex Instruments
CF: CEITEC Nano
See System E is a portable instrument designed for a simple contact angle measurement and surface energy determination. It allows user to measure contact angles of manually deposited sessile drops of up to six different liquids. The software distributed with the instrument, then enables the calculation of the surface energy based on eight different models. Colour UVC camera with high-resolution glass objective lens is used to capture-high resolution images of drops which are then saved in the computer for later analysis.
