Digital Display Plastic Rockwell Hardness Tester (XHRS-150)
XHRS-150 digital plastic Rockwell hardness tester has a novel
appearance and menu-oriented interface. The measuring device adopts
grating sensor and computer control. The hardness value is directly
displayed on the LCD screen. It is a mechatronics hardness
tester.The machine can automatically convert various hardness
parameters, identify the minimum thickness of the test piece,
identify the minimum thickness of the test piece, and determine the
ambient temperature of the test.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 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:
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, laboratory and workshop non-metallic plastics,
hard rubber, synthetic resins, friction materials and softer metals
