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.
Main functions and features:
1. 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
Casting and forging parts ·Sample test and acceptance inspection
Flat and cylindrical workpieces · Steel, non-ferrous metals
Automobile and aviation industry · Cemented carbide, ceramics,
stainless steel
