500 A AC/DC 100kHz Wideband and High-Precision Current Probe for Power Efficiency Testing

SKU: AC/DC CURRENT PROBE CT6845 Categories: , , , , ,


Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6845 is a high-precision 500 A AC/DC current probe that features a wide operating temperature range and large jaw diameter, making them ideal for evaluating the operational integrity of devices that are subject to extreme temperature ranges.

Order Code

CT6845 500 A AC/DC
CT6845-05 500 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

Key Features
