PHR-1ST Portable surface Rockwell hardness testerDetailed product description：

The PHR-1ST portable surface Rockwell hardness tester has small size, light weight, simple operation, accurate measurement, and low price. It has transformed an instrument that originally weighed 100kg into 1-2kg, which can be carried by hand, placed on a desk, or used on a production site; You can take it to the heat treatment plant to inspect the workpiece, take it to the metal material market to purchase materials, or take it on business trips.
The instrument is divided into Rockwell hardness tester and surface Rockwell hardness tester, with a total of 15 scales to choose from depending on the type of metal material. It can test metals ranging from very soft to very hard, test various metal plates, rods, shapes, strips, wire materials, test various metal products and machined parts, with a wide range of applications. The opening width of the instrument ranges from 1 inch to 8 inches, and various metal materials can be tested as long as they can be placed in the instrument opening.
