3-in-1 Hardness Tester GL-420HBRVS-187.5-Y

420hbrvs-185
  • Accuracy compliant with GB/T230.2, GB/T231.2, GB/T4340.2; ISO 6508-2, ISO 6506-2, ISO 6507-2, and American ASTM E18, ASTM E10, ASTM E92 standards.
  • The electronic digital multi-functional hardness tester can simultaneously perform Brinell, Rockwell, and Vickers hardness tests.
  • ARM high-speed processor, 8-inch LCD touchscreen for convenient interface operation
  • Displays current test scale, test force, dwell time, hardness conversion value, and indenter type
  • Automatic application, holding, and release of test force
  • Electromagnetic brake function: applies initial test force, automatically locks the screw and handwheel, then applies the main test force to eliminate human errors and improve measurement accuracy
  • Automatic compensation for test force, high precision force value
  • Automatic correction of concave and convex surface hardness values
  • Software calibration function; dynamic display of displacement-force curve during testing for observation and analysis
  • Upper and lower limits of test hardness can be set, with automatic alert for hardness exceeding limits
  • Various hardness value conversions
  • Equipped with USB and RS232 data interfaces for convenient data processing
  • Data storage function with database synchronization and export capability
  • Compatible with a miniature printer for direct printing of hardness test results
  • Optional PC software for data upload and intelligent control operations
