3-in-1 Hardness Tester GL-HBRVS-187.5-X

hbrvds-187.5
  • One-time molding in the casting process.
  • Automotive paint with strong scratch resistance, remains glossy like new after years of use.
  • Ready to use upon startup, no need to install weights.
  • Large-screen touchscreen LCD display interface.
  • Electronic closed-loop control for applying test force, with force accuracy reaching 5%; force is controlled by force value sensor, with automated operations for applying, holding, and releasing force.
  • Conversion between different hardness values can be performed based on measurements from various scales.
  • The machine body is equipped with a micrometer and a high-definition microscopic optical system, enabling clearer observation of readings and reducing errors.
  • Equipped with a built-in miniature printer and optional RS232 data cable for connecting to a computer via hyperterminal to export measurement reports.
  • Capable of performing Brinell, Rockwell, and Vickers hardness tests with multiple levels of test force, meeting various hardness testing requirements.
