ACR Systems SRP-003-5V-1.5M with extended memory.
The SmartReader Plus 3 easily records AC Current and Voltage (requires separate transducer). Simply connect the logger to ACR's current probes which are then clamped around the conductors, wire the voltage transducer option and begin recording. From this data, total energy consumption (kWh) can be determined for a given period using TrendReader® software. Eight channels (one for internal temperature and seven 0-5V DC channels).
