Adjustable tilt angle of 0 to 60° allows customizable testing for adhesive tapes, films, labels, foams, and other adhesive products. Precision ball positioning ensures accurate initial tack measurements. Innovative grooved ball receiver ring prevents wobbling, while double bracket design enhances stability, reducing vibrations and offsets for reliable results in adhesive testing. Widely used for testing initial tack of pressure-sensitive tapes, medical patches, self-adhesive labels, protective films, foams, and other adhesive materials in the adhesive product industry.
