CHR3000 digital Rockwell hardness tester (convex nose)
The CHR3000 digital Rockwell hardness tester (convex nose) is a desktop Rockwell hardness tester that uses the Rockwell measurement principle for hard
Product details
Functional Features
● High testing accuracy and wide measurement range,
● Upper and lower limit settings, out of tolerance alarm
● Surface correction, automatic correction of cylindrical and spherical measurement results
● The specially designed indenter extends horizontally and can measure parts such as rings and tubes that cannot be measured by ordinary hardness testers. It is easy to operate and 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 experimental 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 settings parameters; Maintain more samples and experimental information
● Adopting modular design for easy maintenance
