echoRD Digital Hardness Testing Machines adopt three testing methods according to Brinell, Vickers and Rockwell. The indentation is measured by digital sensor for automatic hardness values calculations. The instrument is equipped with RS232 interface and built-in printer.

  • The Digital hardness testers, designed and manufactured for completely automatic procedures according to the Brinell, Vickers, Rockwell methods, comply with international standards such as DIN EN, ISO and ASTM.
  • Recommended for all hardness tests with loads ranging up to 3000 (kgf) through video measuring of indentation diameter (HBW) or indentation depth (HBT) without parallax error in the measurement of the penetration points.
  • Imprint detection by 20 position motorized zoom, with transfer of the image to the large LCD touchscreen through internal CCD camera,
  • All hardness values are immediately made available for digital reading.
  • The load cell is electronically controlled for extremely high accuracy test loads.
  • Powerful programmable panel with inbuilt high-contrast, anti-glare, user-friendly color LCD touch-screen.
  • With high levels of repeatability and High measurement accuracy.
