30031 Clamp-on Tester
Shibusawa award for the development on electrical compensation circuit technology, accurately measures a 1mA leakage current

30031
CE
  • Can measure leakage currents of 1 mA, which is useful for checking the insulation of low-voltage circuits and electrical components.
  • Can measure a broad range of currents from leakage currents (at a resolution of 0.001 mA) to load currents up to 60 A.
  • Typical influence (on the current value of an adjacent cable) from an external magnetic field is 0.0005%.
  • Durability of clamp: More than 50,000 opening/closing events
  • Twice the torsional strength of Yokogawa M&C' s earlier model clamps
  • The clamp lever is lengthened by 30%, enabling smooth opening/closing of the clamp even for thick cables of 40mm in diameter.
  • Approved for conformity to safety standards EN 61010-1 (CAT III 300V, pollution degree2)
