PCE Instruments CLL 1 USB Electricity Datalogger 4-20 mA

Model # CLL 1

The 4-20 mA USB data logger PCE-CLL 1 facilitates long-term measurements of electricity of 4 to 20 mA. The USB data logger features an integrated USB interface and records up to 32,000 values.
The USB data logger PCE-CLL 1 features only one key, which guarantees a simple navigation. Since the USB data logger can be either powered by 3.6 V AA batteries or by charging it with an adapter via a computer, a flexible application range opens up.
Thresholds can be set on the USB data logger, and the device features LED warning lights. Thus accurate measuring results can be assured. Even when the batteries are discharged, the saved data does not get lost.
