Convex nose digital Rockwell hardness tester
The convex nose Rockwell hardness tester is a desktop Rockwell hardness tester that uses the Rockwell measurement principle for hardness testing of materials such as carbon steel, alloy steel, cast iron, non-ferrous metals, and engineering plastics. It features automatic loading and unloading of the main test force, digital display and automatic printing of measurement results, or communication with external computers. Widely used in testing, scientific research, and production in industries such as metrology, mechanical manufacturing, metallurgy, chemical engineering, and building materials.
U has high testing accuracy and a wide measurement range,
The specially designed indenter extends horizontally and can measure parts such as rings and tubes that cannot be measured by ordinary hardness testers. The minimum tested inner diameter is 15mm
Easy to operate, available in any language version
Ready to use upon startup, no need to install weights, no need for installation and debugging
Electric loading, closed-loop control
Automatic correction of test force, increasing the accuracy of force by an order of magnitude
All Rockwell scales have automatic correction for high, medium, and low hardness values
Set password protection parameters; Maintain more samples and experimental information
U adopts a modular design for easy maintenance
