SmartReader 3 Data Logger
Manufacturer : ACR Systems

ACR Four Channel Logger: One channel ambient temperature and three channels for AC current probes

The SmartReader 3 data logger makes easy and accurate recordings of AC current. You can use this logger with up to three external current probes for recording three-phase systems or related equipment simultaneously. The easy-to-use ACR CTs provide safe current readings by simply clamping around the power leads.
