Hioki clamp sensors are best-in-class measuring devices incorporating Hioki's expertise in current sensing technology. The CT7040 Series compromise of 600A,6000A AC flexible current sensors in three different loop sizes that pair with the detachable Display Unit to measure large currents in crowded wiring and confined spaces. 

 CAT IV 600 V, CAT III 1000 V 

 Key Features  
- Thinner cables are easier to use in confined spaces and with complicated wiring 
- Supports large current measurements up to 6000 A 
- Wide 10 Hz to 50 kHz band with excellent frequency characteristics 
- Choose from three conductor diameter sizes
- Ideal for site inspections by using detachable Display Unit - Four output formats to output data to loggers or other devices (via Display Unit): WAVE, RMS, PEAK, Hz
