C138M Universal digital tester with microprocessor for load cells

( Concrete )
  • UNI 6326
  • DIN 51220
  • NF P18-411
  • ASTM E74
  • BS 1610
  • EN ISO 376

This user-friendly menu-driven digital display, connected to load cells (mod. C140 to C140-10 and mod. C142 to C142-08) allows an accurate verification of the loads measured from machines under control and it allows to production of the corresponding certificate.
The instrument foresees three memorized cycle verification programs composed of ten measurements each.
At the end of the test, the unit automatically elaborates the stored value and displays:

  • Effectively applied load
  • Measured load (over three verification cycles)
  • Average measured load
  • Accuracy in %
  • Repeatability
  • Relative readability
  • Max error
  • The tester’s accuracy is ± 0.5% of the indicated load.

The apparatus and all the accessories are contained in a strong and practical suitcase, immersion resistant with a depressurisation valve.

Power supply: 110-230 V 1ph 50/60 Hz
Dimensions: 360x300x200 mm
Weight: 5 kg approx.
