Introducing the SPT-AD21 Adhesion Tester, a compact and reliable instrument designed to measure the force required to peel a standard test tape from various surfaces. This tester, with its size that is perfect for portable use, is an essential tool for quality control applications in industries such as electronics, coatings, and automotive.
The SPT-AD21 Adhesion Tester features a clear, easy-to-read LCD display that shows the force reading in grams (-1 scale). The tester's digital interface ensures accurate and consistent readings, making it a reliable instrument for measuring the adhesive strength of various materials.
The test tape used with this instrument is a standard 50mm x 25mm, with a pressure-sensitive adhesive backing. The tape is attached to the tester's applicator roller, which evenly distributes the tape onto the surface being tested. Once the tape is pressed down and allowed to adhere to the surface for a few seconds, the user can then apply a steady, even force to the handle of the tester to peel the tape away.
The force required to peel the tape is then displayed on the LCD screen, providing an instant reading of the adhesive strength of the surface being tested. This information can be used to evaluate the effectiveness of adhesives, coatings, or primers, ensuring that they meet the required specifications for various applications.
The SPT-AD21 Adhesion Tester is powered by two AA batteries (not included), and comes with a convenient carrying case for easy transportation and storage. The tester's compact size, combined with its accuracy and ease of use, make it an indispensable tool for professionals in the fields of quality control, research and development, and manufacturing.
