Shanghai Aolong Xingdi Testing Equipment Co., Ltd. newly launched "Aolongxin" large platform automatic Rockwell Hardness Tester MHRS-150-Z, using international professional closed-loop sensor control technology, to achieve fully automatic control and hardness testing process. The loading system adopts a high-precision force value sensor and a central controller to form a closed-loop loop to realize the whole process of microsecond tracking and control of afterburner.
THE BATHYMETRY SYSTEM USES A HIGH-PRECISION DISPLACEMENT SENSOR, WHICH RESULTS IN A MINIMUM HARDNESS VALUE WITH A RESOLUTION OF 0.1 HR. The position of the indenter is fixed, and the hardness test is carried out by the movement up and down the platform. The overall movement of the large platform eliminates the gap generated when the lead screw is lifted, greatly improves the accuracy and repeatability of the test, and also increases the stability and efficiency of the machine. The new foot switch function, one-button measurement, saves a lot of manpower, and is convenient for on-site use.

●Comply with ASTM E18, ASTM E384, ISO 6508, GB/T230;
●The frame structure is firm and rigid;
●Fully automatic closed-loop sensor loading;
●It can test 15 kinds of Rockwell hardness scales;
●High precision, international contrast is less than 0.5HR;
●High-speed step control, extremely fast test speed;
●With foot switch design, the overall automatic lifting of the large platform saves manpower, and one-button automatic measurement;
●High-precision loading system, effectively avoiding force overload, and greatly improving the loading speed;
●The test process curve display can visually display the material characteristics, which is convenient for observation and learning;
●It can be continuously measured in and out of the fixed workbench through the automatic withdrawal function of the indenter;
●The automatic lifting platform and the automatic load initial test force can ensure the stable generation of the force;
●High-definition LCD, touch screen operation, menu-based operation interface;
●Automatic loading and unloading, holding time adjustable;
