Hardness Tester

• 2 in 1 impact device D + DL for measurements on small and hard accessible points
• Mountable DL probe (Ø 4 mm, length 50 mm)
• Large measurement range
• High accuracy ±2 HL
• Easy to calibrate
• Very large memory
• Re-chargable battery
• Applicable under extreme conditions (-40°C to 80°C)

Measuring Principle

During the measuring process, the sensor makes inline movements along the probing path. The stylus moves up and down in accordance with the probing path profile. These movements are translated into electric signals, which are amplified, filtered and converted into digital signals using an A/D converter. The CPU then processes these signals as Ra and Rz results (or Rq and Rt results) and shows them on the display.
