Portable Aluminum Hardness Tester Barcol Hardness Tester For Aluminum Alloys Copper , Easy Operation

Operating information:

1.The hardness tester is best suited for testing homogeneous materials.Materials of granular.fibroud or coarse struture will produce a wide variation in hardness readings because of the small diameter of the ienter point.

2.For accurate readings,material should be atleast 1/32"thick and large enough for a minimum distance of 1/8" in any direction from the indenter point to the edge of the specimen.The testing area should be smooth and free from mechanical damage.

3.Simply exert a light pressure against the instrument to drive the spring-loaded indenter point into the material.The indenter point must be perpendicular to the surface being tested.

4.On very soft metals,the highest reading should be used since cold flow permits the spring-loaded indenter point to continue penetration.
