Digital Surface Rockwell Hardness Tester (HRMS-45)

The HRMS-45 digital Rockwell hardness tester has a novel appearance and a menu-oriented interface. The measuring device adopts a grating sensor and computer control. The hardness display value is directly displayed on the LCD screen. It is a mechatronics hardness tester.This machine can automatically convert various hardness parameters to each other, identify the minimum thickness parameters of the test piece, identify the minimum thickness of the test piece, and determine the ambient temperature of the test. It has the characteristics of simple operation, small indentation and high precision, etc.Built-in printer to read relevant test results. Automatic operation is realized, and human operation and reading errors are eliminated.

Directly display the test hardness value through the large LCD screen;2. The shell is made of one-time molding and casting by a special sand-finding process, with a stable structure and no deformation, and can work in a relatively harsh environment; the car paint has high grades, strong scratch resistance, and it is still bright as new after many years of use;3. We have the ability to develop, design, produce and process by ourselves, and provide parts replacement and maintenance and upgrade services for the machine for life;

Main purpose and scope of application:

Surface hardened steel, copper, aluminum alloy sheet, strip steel, hard alloy steel

Various metal materials such as zinc plating, chrome plating, tin plating, material surface heat treatment and chemical surface treatment
