Ac/Dc Auto-Zero Current Sensor CT7731 - Accurate, Long-term Recording and Easy Output Settings

Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CT7731 is a 100 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 or CM7291 for convenient field testing, while delivering an extended temperature range and auto-zero adjustment to minimize drift due to wide temperature changes that occur during long-term testing. Further extend the functionality of this system by connecting the Display Unit with a Hioki memory recorder or logger. CAT IV 600 V
