Hioki CT6841A AC/DC Current Probe

Overview

The Hioki CT6841A is an AC/DC clamp-type current sensor designed for precision current measurement in battery-powered systems and power conversion applications. It connects directly to Hioki Power Analyzers and Memory HiCorders, eliminating the need to cut or interrupt circuit lines under test. The sensor uses flux gate detection technology for accurate DC current measurement across a wide temperature range, making it particularly suitable for EV battery efficiency testing and PV power generation system evaluation.
