Functional Features
The rack structure is sturdy and has good rigidity
● Fully automatic closed-loop sensor loading
Test 15 Rockwell and 15 surface Rockwell hardness scales
High precision, international contrast less than 0.5HR
Compliant with the standard ASTM E18, ISO6508, GB/T230.2
New design with downward pressure on the nose.
High precision loading system effectively avoids force overload during measurement.
● Continuous measurement can be carried out on the fixed workbench through the automatic retraction function of the pressure head
The automatic lifting of the machine head and automatic loading of initial test force can ensure stable force generation.
● High definition LCD touch screen operation, menu based operation interface
Backlit LCD display, automatic data statistics and storage, RS-232 data output interface.
● Automatic loading and unloading, with adjustable holding time
● GO/NG tolerance judgment.
Correction of test values for cylinders and spheres
The selection of force measurement is linked to the selection of hardness scale.
The selectable operating languages include English and Chinese, which are convenient for users to operate.
● Scale conversion to HR, HB, HV, and tensile strength
● Built in printer.
The standard configuration is complete and can meet the testing requirements of all rulers
● Fully automatic closed-loop sensor loading system, fixed test bench, achieving high-precision and fast testing, and can also provide higher-level standard hardness testers
