Hioki CM7291 Display Unit (Bluetooth®)

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

The Hioki CM7291 is the wireless receiving/display and output unit for the CT7600 and CT7700 AC/DC Current Sensor series, creating a standalone clamp meter for field use or enabling waveform signals to be output to a Hioki memory recorder or logger for further analysis.

Key Features

  • Send measured values to a smartphone or tablet using Bluetooth® wireless technology
  • Use the GENNECT Cross dedicated app to display and review measured values and waveforms in real time
  • Power supply and signal output for Current Sensor CT7000 series
  • Simultaneous dual display of the measured values, frequency, and output rate
  • Four output formats to output data to loggers or other devices (via Display Unit)
  • Supports AC adapter, AA alkaline batteries, and external power supply
