HRSS-150ZU Fully Automatic Rockwell & Superficial Rockwell Hardness Tester

The test force is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit replace traditional dead weights. The result is highly accurate hardness test measurements at all test loads up to 0.5%.
Simple plug – and – play tech allows for much more quick and easy installation than traditional dead weight type machines.
AutomatedZ-Axis. Just press START key once, entire test process will be finished automatically. Regardless of the size of the sample, the position of the sample, the distance between the indenter and sample surface. The sample will be auto-lifted to approach the indenter and finish hardness tesing automatically.
Higher precision than handle wheel lifting/dead weight type machines which can be affected by user interaction.
Extended dolphin nose allows vertical hardness test height of 11.8” and throat depth of 8.6”.
Built-in micro-printer.
