Feature

●This Hardness Tester has been designed for the measurement of the hardness of protective coatings. The degree of hardness of paint films, plastic coatings. etc.
●The measured surface can be selected arbitrarily, no matter whether on a level or curved surface, small or large.
●The Hardness Tester is easy to operate, stable performance.
●The Hardness Tester is always ready for use. It is carried in the pocket, an asset which will be appreciated by all concerned with hardness tests.
●The Newton Hardness Tester provides the engineer, foreman, inspector and others with a test instrument that satisfies the requirements of smooth production runs.


Description

Features
The measured surface can be flat or curved.
Not limited by area size.

Easy to carry and other characteristics.

Principle
The spring compression deformation, the force generated by the load on a known diameter of the test head, with the test head to mark the coating surface to be tested to check whether the coating surface is damaged, the test results in Newton.
