Product Description
HR-150A double handle type is another fundamental model of all rockwell types,it is favored by most customers mainly because of its mechanical and manual testing mode,which is durable and stable.
Without electrical power supply,and with simple designed appearance and single handle,it is very easy to operate,as well as economical and practical performance and wide using scope.
There is no parameter distinguish between single and double handle type,it only depends on the user's operation habit and personal hobby.
Using Scopes:
● Rockwell Hardness Testing of Ferrous Metal,Non-ferrous Metalt and Non-metallic Material.
● Hardened and surface hardened steel, hardening and tempering steel, tempered steel, cold and hard casting parts, forging parts, hard alloy steel, aluminum alloy,bearing steel, carburized steel sheet, etc.
Feature:
● Easy to use, and the test force can be applied and unloaded by a handle;
● Dial direct reading, HRA, HRB, HRC scale;
● Other scales of Rockwell are optional;
● High precision of indication, easy installation and low failure rate

● A scale: It is suitable for testing the metal more than 70HRC, such as tungsten carbide, hard alloy as well as the hard sheet material and the hardening material on the surface layer.
● B scale: It is suitable for testing non-ferrous metals and alloys, annealing steel or soft or medium hardness of materials.
● C scale: It is suitable for testing the carbon steel, tool steel and alloy steel.
