JMHRS-150-XYZ Automatic Rockwell Hardness Tester is a new head-pressed Rockwell Hardness Tester manufactured in CHINA, which adopts professional closed-loop sensor control technology to achieve fully automatic control and hardness testing process.
The loading system adopts a high-precision force sensor and a central controller to form a closed-loop loop to realize the continuous tracking and control of the afterburner process throughout the process.
THE BATHYMETRY SYSTEM USES A HIGH-PRECISION DISPLACEMENT SENSOR, WHICH RESULTS IN A MINIMUM HARDNESS VALUE WITH A RESOLUTION OF 0.1 HR. The stage is fixed, and the hardness test is performed by the upward and downward movement of the indenter. The fixed test bench can eliminate the coaxiality error caused by the traditional screw rotation up and down, greatly improve the accuracy and repeatability of the test, and also increase the stability and efficiency of the machine.
The test process is fully automated, put multiple samples on it, and press the "start" button to obtain multiple hardness values for each sample.

●The frame structure is sturdy and rigid
● Fully automatic closed-loop sensor loading
● Test 15 types of Rockwell scales
● High precision, international contrast is less than 0.5HR
●Conform to ASTM E18 ISO6508 GB/new design, nose push-down type.
●High-precision loading system, effectively avoiding force overload.
●The automatic head can be continuously lifted and the initial test force of the automatic load can be carried out in and out of the fixed workbench through the automatic withdrawal function of the pressure head, which can ensure the stable generation of the force measurement.
●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, holding time adjustable
●GO/NG tolerance judgment.
●Correction of test values for cylinders and spheres
●The force measurement selection is linked to the hardness scale selection.
●Optional operating languages include English and Chinese for easy user operation.
●Scale conversion HR, HB, HV and tensile strength
● Built-in printer.
●The standard configuration is complete, which can meet the test requirements of all scales
●Fully automatic closed-loop sensor loading system, fixed test bench, to achieve high-precision and rapid testing, can also provide a higher level of standard Hardness Tester
