Features of KHT800-A Automatic Rockwell Hardness Tester

Closed-Loop Force Control: The Lanetech KHT800-A employs a sophisticated closed-loop system (load cell + DC motor + electronic control unit), eliminating traditional weights. Ensures exceptional precision with 0.5% accuracy across all test loads.
Plug-and-Play Installation: Enables 60% faster setup vs. weight-based machines – zero professional calibration required.
Fully Automated Testing: Single-button Z-axis auto-focus initiates autonomous operation. Self-adjusts for sample size, position variance, and indenter-sample distance. Auto-elevates specimens for hands-free testing.
Precision Advantage: Surpasses manual/wheel-operated testers by eliminating human error.
Dolphin Nose Design: 300mm vertical clearance + 220mm throat depth accommodates oversized components.
Monolithic Cast Construction: Reinforced base and integrated casting deliver permanent mechanical stability.
Data Management: Features built-in micro-printer + USB connectivity for real-time report export to PCs.
This rockwell hardness method surpasses the precision of manual wheel lifting or dead weight-based machines, which are susceptible to variability based on user handling.
Additionally, this type of automatic rockwell hardness tester is equipped with an in-built micro-printer and a USB connection for PCs, facilitating convenient data documentation and transfer.
