Hioki Launches AC/DC Current Probes with Breakthrough Accuracy and Compact Design for Automotive Power Testing

Hioki E.E. Corporation announces the launch of the AC/DC Current Probes CT6833 and CT6834, next-generation clamp-type sensors designed to set a new benchmark in precision and usability for automotive power testing. These probes are 50% smaller than Hioki’s existing CT6843A and CT6844A models, offering superior usability and flexibility for even the most space-constrained environments. Designed to support Worldwide Harmonized Light Vehicles Test Procedure (WLTP) and SAE J1634 standards, the CT6833 and CT6834 empower automotive manufacturers and testing laboratories with unparalleled accuracy and improved ease of installation.

The WLTP and SAE J1634 standards ensure globally harmonized protocols for measuring fuel and electricity consumption, emissions, and energy efficiency. These regulations require precise current (Ah) or power (Wh) integration for recharging and discharging vehicle batteries. The compact, refined design of the CT6833 and CT6834 enhances installation workflows, reduces setup times, and ensures reliable results, even in the crowded engine bays of modern vehicles (more info).
