The UNI-T Flexible Clamp Sensor UT-CS09D delivers precise AC current measurement across three ranges—30A, 300A, and 3000A—making it ideal for comprehensive electrical diagnostics. Its 45.7cm flexible clamp accommodates various conductor sizes with ease, while the CAT IV 600V rating ensures safe operation in demanding industrial environments. Operating reliably between 0°C and 50°C, this sensor maintains accuracy across a 45Hz–500Hz frequency range. Weighing just 260g, it's portable yet robust, powered by three standard R03 batteries with low-battery indication at 3.3V. Includes batteries, BNC adapter, and English manual for immediate deployment.

The UT-CS09D Flex Clamp Sensor employs advanced Rogowski coil technology to measure AC currents up to 3000A with exceptional stability and safety. Its flexible 45.7cm clamp design navigates confined spaces and irregular conductor configurations where rigid sensors fall short. Built for professional electricians, this lightweight instrument delivers reliable measurements across industrial applications while maintaining CAT IV 600V safety certification. The three selectable ranges (30A, 300A, 3000A) and 45Hz–500Hz frequency response ensure accuracy across diverse electrical systems. Compact at 260g and powered by standard batteries, it's engineered for field efficiency without compromising measurement integrity.
