More InfoQuote

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

The CT7631 is a 100 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 to capture instantaneous waveforms that can be output to a Hioki memory recorder or logger for further analysis.

Note: CT7600 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.
