The Rangemaster

  • Large digital readout.
  • Hardness values displayed in all major international scales.
  • Value above or below tolerance indicators.
  • Last reading recall facility.
  • Battery or mains power.
  • RS232C output for connection to SPC equipment or serial printer for data collection and treatment of results either as an ongoing process or at the end of a batch of readings.
  • Storage capacity for over 400 readings. Can be downloaded to a serial printer for comprehensive test reports.
The Rangemaster

First portable, digital hardness tester of its type, the Electromatic Rangemaster has the advantage of redesigned mechanics and improved microprocessor control technology for high accuracy and repeatability. One instrument includes British, American and German standards with hardness values in Vickers, Brinell, Rockwells B and C, and tensile strength.

Based on the well proven principles of the instrumatic, a mechanical load of 15kg is applied in two stages to a diamond indentor through special pre-loaded springs. The indentor penetrates the test surface to a maximum depth of only .005", reducing damage to an absolute minimum yet giving consistently accurate results.


Mode Functions
  • Mode Key: select upper/lower tolerances; prints out stored readings; clears memory; sets date/time; selects calibration mode.

  • -/Cancel Key: cancels previous reading,changes limits, date, time and calibration value.

  • +/Recall Key: recalls previous reading, changes limits, date, time and calibration.

  • Set Range Key: selects the testing range required; sets the mode value in memory.

Hardness Scales:
The Rangemaster features five international hardness scales as standard (all in one unit) for a wide range of applications.
