Hardness Testers

INATEST - NEW portable programmed ultrasonic hardness tester

Hardness tester InatestNew hardness tester, based on UCI method and intended for express hardness measurements in laboratory, workshop and etc. 

The distinctive instrument feature is absence of hard requirements to the cleanness and form of surface and positioning of sensor. Construction of indenter, allows to produce the stable measurings without depending on effort and time of pinning of sensor to the surface, providing exact measurings without application of stand. 

Instrument allows to measure hardness of metals (steel, cast-iron, coloured metals and other), superficially consolidated layer (cementation, nitriding, etc.), and also galvanic coverages (chrome). Easy, in one button pressing, changing of scale provides rapid measuring on all basic scales: Brinell (HB), Rockwell (HRC, HRA, HRB), Vickers (HV), Shor(HSD). 


  • Memory: up to 6 000 results of measurements
    with possibility of their transfer to PC
  • 3 additional scales of hardness
  • Averaging of results of measurement
  • Automatic switching-off
  • Graphic LCD with bightness correction
  • Mains power: build-in rechargeable battery
  • 3 year warranty

Basic Delivery Set

  • Inatest base unit
  • B-type probe (50N)
  • Power unit/ charger
  • PC cable
  • Software
  • Protective cover
  • Transport bag

Additional accessories

  • N-type probe with the diminished loading (only 10N) - for control of wares with enhanceable requirements to the size of imprint, galvanic coverages
  • S-type probe with the megascopic loading (100N), for control of wares with a badly geared-up surface
  • Shortened K-type probe with the diminished sizes (height - 70mm), for control into pipes, difficult of access places.
  • Hardness calibration blocks
  • Stand for a probe
