Judgement

“Quick check” function now even more advanced. Comes with Pass/Fail Judgment color display, for easy result checking. Routine torque wrench inspections at line-side test stations are now easier and more accurate with Tohnichi’s digital torque wrench checkers in the LC3/LC3-G line checker series.

LC200N3

LC1000N3

The color on the display panel indicates Pass or Fail. Easy recognition.

White: Now evaluating  Blue: OK (Pass)  Red: NG (No good)

Application

  • Tightening assurance system for torque wrench accuracy checks (routine inspections) at line-side test stations.
  • Calculates when the next calibration should be (preventive maintenance).
  • The LC20N3 can also be used as a torque checker for torque screwdrivers.

Features

  • Different colored LCD display visibly notifies judgment results.
  • Wide measurement range, reasonably priced, compact and high accuracy.
  • Can read actual running torque (Patented).
  • Built-in statistical processing functions.
  • Statistical processing functions automatically calculate sample numbers and maximum, minimum and mean values.
  • Hex adapters can be combined to test different sized open-end torque wrenches.
  • Power source AC100V-240V±10% to cover international use.
  • Battery pack is available as an option.
  • Support use in the EU.
  • With CE marking.
  • We have experience manufacturing products with American units of measurement (lbf, in, etc.) for Japan’s aircraft manufacturing industry and for export to the U.S., and products with metric units of measurement (kgf, cm, etc.) for export to other parts of the world.
