The 318 hardness tester is used to measure the hardness of protective coatings, paint films, plastic coatings, wood or metal surfaces. The measuring surface can be flat or curved, regardless of size. The instrument is always on standby, it can be carried in a pocket and used for various hardness tests. Uniform hardness and coating quality facilitate rapid production, and the instrument complies with routine quality control of protective coatings, even during production. The 318 hardness tester provides engineers, pipefitters, monitoring personnel and other related personnel with a test instrument that can meet various needs of smooth production operations."}
