CHR3100 digital surface Rockwell hardness tester (convex nose)
The CHR3100 digital surface Rockwell hardness tester (convex nose) adopts the Rockwell measurement principle and is used for hardness testing of mater
Product details
Functional Features
High testing accuracy and wide measurement range;
● Upper and lower limit settings, over tolerance alarm;
Surface correction, automatically correcting the measurement results of cylindrical and spherical surfaces;
The specially designed indenter extends horizontally and can measure parts such as rings and tubes that cannot be measured by ordinary hardness testers. The inner diameter of the workpiece is ≥40mm is sufficient for measurement；
● 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 values 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 a modular design for easy maintenance
