Product Description:
The MR521 is a general purpose 1500AAC or DC current probe designed for use with DMMs, loggers, oscilloscopes and other instruments that have voltage inputs. The MR521 has dual selectable range probes. The MR521 has an integral 5 ft (1.5m) lead terminated by shrouded banana plugs. The jaw design on these probes make then well-suited for measuring current in both cable and bus bar type conductors.
