Colswe Amp Logger is a digital USB ampermeter that measures current automatically. It can provide quite precise digital measures (2 mA, 1%). It measures direct current (DC) as well as alternating current (AC) for which it provides the RMS value (5 mA or 3%).
Colswe Amp Logger is isolated, which means that the sensing part is electrically disconnected from the USB part: you can measure any current including from the mains, without a risk of damaging your PC.
Colswe Amp Logger Measurements can be read directly via an USB connection or stored the measurements in its internal flash memory for later retrieval via the USB connection.
