HOBO® Energy Logger Pro True RMS Module

FlexSmart True RMS Current/Voltage Module

The FlexSmart True RMS Module mounts on the top of the logger and accepts 2 channels of AC Current and/or Voltage from sensors with 333mV FS output. Each channel can be configured separately. The result is high accuracy measurements of sinusoidal as well as non-sinusoidal wave forms associated with variable frequency drives and similar equipment.
