DCAT?25SF Tensiometers

​The DCAT 25SF Tensiometers is a specialized dynamic contact angle measuring instrument and tensiometer developed by DataPhysics Instruments, meticulously designed for high-precision analysis of single fibers. Building upon the robust foundation of the DCAT 25, the 25SF variant incorporates advanced features to facilitate accurate measurements on delicate samples such as carbon or glass fibers.
