Flex Sensor High-Current 3000A AC – UNI-T UT-CS09D

The Rogowski Coil Advantage

Traditional hard-jaw clamp meters often struggle in crowded electrical cabinets or with large busbars. The UT-CS09D features an 18-inch (45.7cm) flexible coil that can be easily looped around heavy cables and irregularly shaped conductors. Because the coil is non-magnetic, it is immune to saturation, ensuring linear and accurate readings even at the highest current levels.

Universal Compatibility & Precision

While the UT-CS09D is designed for seamless “plug-and-play” use with UNI-T’s UT206B and UT208B clamp meters, its standard BNC/Banana adapter makes it compatible with almost any digital multimeter or oscilloscope. It offers three manual ranges (30A, 300A, and 3000A), allowing you to tailor the sensitivity to your specific application, from residential load centers to industrial power grids.

Built for Industrial Reliability

Safety is paramount when working with high-voltage systems. The UT-CS09D is CAT IV 600V rated and features a robust terminal connection to prevent accidental disconnection. Its lightweight, 260g design reduces hand fatigue during extended diagnostic sessions, and it is 1m drop-proof, making it a rugged addition to any professional’s toolkit.
