Consistent, High-precision Current Testing Across a Wide Temperature Range

SKU: AC/DC CURRENT PROBE CT6841 Categories: , , , ,


Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6841 is DC to 1 MHz/20 A sensors, ideal for capturing signals during the efficiency testing of batteries, inverters and power conditioners.

CT6841 20 A AC/DC
CT6841-05 20 A AC/DC, 12 pin terminal, for the PW6001 only

Note: These products cannot be used alone. The optional 9555-10 is required in order to supply power and connect the clamp to a Memory HiCorder or other instrument. Products can be directly connected to the Power Meter 3193-10 and Power Analyzer 3390 (Does not support Model 3390-10).

CEInsulated Wire
