DigiRock DR4 Digital Touchscreen Rockwell Hardness Tester

Sinowon · SKU sinowon-DIGIROCK-DR4

The DigiRock DR4 is a semi-automatic Rockwell hardness tester: only the initial load is applied and the force knob switched by hand, with the rest of the cycle running automatically. Its color touchscreen shows load force, indenter type, dwell time and conversion scale, while motorized loading, dwell and unloading eliminate operator error. A built-in microprocessor automatically computes maximum, minimum, mean and deviation with 0.1 HR resolution, and automatically converts hardness to other scales. It stores 2,000 individual results and 1,000 group results for review and analysis, with an optional Bluetooth printer.
