AC/DC Current Sensor

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. CAT IV 600 V Key Features • Ideal for observing instantaneous waveforms in laboratories and other temperature-controlled environments • 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

Model No. (Order Code)

CT7631	100 A AC/DC, φ33 mm (1.30 in)

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.

Connect to Recorders, Data loggers, and Oscilloscopes

The CT7000 series cannot be used alone. Use with the Display Unit CM7290, CM7291 to connect with Data Loggers and Memory HiCorders.
