KHT900-A Automatic Rockwell Superficial Hardness Tester

Features of KHT900-A Automatic Rockwell Superficial Hardness Tester

• Closed-loop control (load cell, DC motor, electronic unit) replaces weights, ensuring high accuracy (≤0.5%) at all test loads.

• Plug-and-play technology enables faster, easier installation vs traditional weight machines.

• Automated Z-Axis: Single START key initiates full automatic testing cycle, independent of sample size, position, or indenter-sample distance. Auto-lift positions sample.

• Higher precision than manual/dead weight machines, eliminating user influence.

• Extended dolphin nose allows 300mm vertical height and 220mm throat depth.

• Integrated casting body with wider base ensures permanent stability.

• Built-in micro-printer and USB port for PC connection.

• Rockwell hardness method
