The PGX+ is a compact, video-based instrument that measures the wetting and absorption of virtually any size or shape surface without the need to prepare sample strips. Eliminating the need to cut your material makes it ideal for any product that is difficult to cut such as rigid components, drywall board, glass or the inside of a container. It also performs nondestructive testing so can be used on expensive materials without damage.
Determine the static contact angle at “equilibrium” or use a sequence of images to measure the dynamic wetting, rate of sorption and spreading as a function of time. The PGX+ software measures surface tension of the test liquid, calculates the surface energy of a solid and includes a report generator. The PGX+ is connected directly to the USB port of a laptop or a desktop computer.
