Product Features & Applications
Product Features:
MRocky-150/45AAutomatic Rockwell hardness tester adopts a brand-new loading structure with high-speed head lifting, delivering extremely high testing efficiency to meet various specimen testing requirements, especially suitable for large workpieces.
Featuring a novel appearance, complete functions, convenient operation, intuitive display, and stable performance, it is a high-tech mechatronic product.
Supports all Rockwell and superficial Rockwell hardness scales.
Enables multi-value conversion of hardness scales.
Equipped with arc correction and compensation function.
High-speed head lifting, automatically adjusts descending speed upon sensing the specimen, and applies test force smoothly.
Touchscreen display and operation with dynamic curve graph for real-time monitoring of force sensor and displacement sensor status.
One-key operation for head descending, indenter loading, dwell, unloading, and hardness value display.
Marble platform for higher flatness.
Data storage function, automatically calculates maximum, minimum, average, standard deviation and repeatability; test results can be selectively deleted and output; built-in thermal printer, and Excel data files can be exported via USB.
Product Application:
Suitable for hardness measurement of quenched, tempered, annealed, hard castings, malleable castings, hard alloy steel, aluminum alloy, copper alloy, bearing steel, etc. Also applicable to surface quenched steel, surface heat-treated and chemically treated layers of materials, copper and aluminum alloys, thin plates, galvanized, chrome-plated, tin-plated materials, bearing steel, hard castings, etc.
