PHR-100 Magnetic Rockwell Hardness TesterDetailed product description：

PHR-100 Magnetic Rockwell Hardness Tester

Overview

*The world's first Rockwell hardness tester designed based on the principle of Rockwell hardness testing, which can test the hardness of metals by simply contacting the specimen on one side.
*By relying on magnetic force to attach the Rockwell hardness tester probe to the steel surface, there is no need to support the sample.
*The testing accuracy meets the standards of GB/T230 and ISO6508, and is not lower than that of a desktop Rockwell hardness tester.
*Testing is fast, easy, and does not require sampling. As long as there is a flat or curved surface where the instrument can be placed, any large workpiece can be tested.
*The test values meet the product standards or drawing requirements of most workpieces without the need for conversion.
*In most cases, it can replace the low precision Leeb hardness tester.
Scope of application
*Used for testing steel workpieces.
*Large workpieces that can be tested and assembled, cannot be cut, and are inconvenient to move, such as large molds, steel plates, steel pipes, steel structures, boilers, pressure vessels, metal pipelines, etc
*Can test the hardness of welds and heat affected zones.
*It can directly test flat specimens and add an optional adapter to test corresponding diameter pipe specimens.
*It can be tested on a horizontal plane, as well as on inclined or vertical surfaces.
