HIOKI ST5541 Leak Current HiTester

Leak current measurement, an essential part of electrical safety (For Standard- and Regulation-compliant)

LEAK CURRENT HiTESTER ST5541: A low-cost solution that complies with standards governing general-use electrical devices. Uninterrupted polarity switching function dramatically reduces cycle time. Support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards. Touch panel features simple, interactive operation. Communications functionality and external I/O support allow automatic testing on production lines.

Note: For applications involving leak current measurement of medical-use electrical devices, use the ST5540.
