Extech Multi data logger DL160 Messgr

With the dual data logger, you can measure, record, and monitor alternating voltage and current values independently over long periods. The inputs can be configured in any combination (voltage/voltage, current/current, or voltage/current). The stored data can be transferred, saved, and analyzed on a computer via the USB interface. The display shows the current measurement values as well as the min/max data with timestamps.
