Hioki CT7040 Series AC Flexible Current Sensor
Hioki clamp sensors are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology.
The Hioki 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
Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)* It is waterproof to maintain measurement function, and measuring the live part in wet condition increases the risk of electric shock.
