PHR Small portable Rockwell hardness testerDetailed product description：

PHR small portable Rockwell hardness tester

The PHR series portable Rockwell hardness tester is a technological advancement in the field of hardness tester manufacturing. The instrument is designed based on the basic principles of Rockwell hardness testing, achieving miniaturization and lightweight of traditional hardness testers while maintaining testing accuracy, with a minimum weight of 0.8 kilograms.
*The testing range of the PHR series portable Rockwell hardness tester includes: very soft aluminum, lead, tin, medium hardness aluminum alloys, copper, copper alloys, low carbon steel, stainless steel, very hard alloy steel, carburizing steel, hard alloys, etc., covering almost all common metals.
*The Rockwell hardness tester has small indentation and can be used as a non-destructive testing tool to directly test workpieces.
*This Rockwell hardness tester is easy to operate and flexible to use. Can be used like a micrometer. Various small and medium-sized metal parts, as well as large workpieces such as plates, belts, rods, and tubes that are too long, too heavy, and difficult to move, can be tested as long as they can be placed in the instrument opening, and their application range is very wide. The instrument is suitable for piece by piece inspection of finished or semi-finished workpieces processed in batches, and can be used in production sites, sales sites, and material warehouses.
*This Rockwell hardness tester can directly test the hardness of the inner and outer surfaces of pipes.
*The Rockwell hardness value can be converted into Vickers (HV), Brinell (HB) hardness values or tensile strength (σ b) values by looking up a table.
*According to testing by the China Institute of Metrology, the error is less than 1.5HRC.
