AC/DC CURRENT SENSOR CT7631
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 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.

Model No. (Order Code)

CT7631100 A AC/DC, φ33 mm (1.30 in)
CE

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.

CAT IV 600 V
Key Features

• Ideal for use in environmental testing with broad -40˚C to 85˚C temperature range
• High precision with a clamp-type design, ±0.3% amplitude accuracy, ±0.1° phase accuracy
• Wide-bandwidth DC to 500 kHz
• Single-handed operation and robust locking mechanism
• Reduced effects from magnetic fields, conductor position, and noise from nearby wires
• For EV/HEV battery charge and discharge efficiency measurement and inverter and power conditioner conversion efficiency evaluation


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.
