The HOBO Plug Load logger is designed to monitor energy consumption of AC-powered plug in
loads. This compact device can be used as a power meter with its built-in LCD for real-time
energy monitoring or as a data logger that can record up to 1.4 million measurements for
analysis. With the ability to view or log true RMS voltage (V), true RMS current (A), active
power (W), active energy (Wh), apparent power (VA), and power factor (PF), the HOBO Plug
Load logger provides you with an accurate log of your energy consumption of plug loads. Using
HOBOware®, you can also easily configure the logger to calculate minimum, maximum, and
average statistics during logging at a fixed sampling rate of 16.67 mS.
