The Yokogawa model 30031 is a rugged and durable tester ideal for the most demanding applications. Its clamp is rated at more than 50,000 opening/closing events. The Clamp lever is lengthened by 30%, enabling smooth opening/closing of the clamp even for thick cables of 40mm in diameter, it also has twice the torsional strength of Yokogawa M&C' s earlier model clamps. The unit can measure leakage currents of 1 mA, ideal for checking the insulation of low-voltage circuits and electrical components and is hiighly accurate. The typical influence (on the current value of an adjacent cable) from an external magnetic field is 0.0005%.

CL300 series and 30031 have basic function of leakage current measurement. These clamps allow you to measure current range from 3mA to 1000A. Choose your desired diameter of measurable conductor from 24mm to 68mm.
