Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology.

The Hioki CT7731 is a 100 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 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

Note: CT7700 series cannot be used alone. Use with the Display Unit CM7290, CM7291 to connect with Data Loggers and Memory HiCorders. When used in combination with CM7290 or CM7291, the frequency band of current display and waveform output becomes narrow.
