Description
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).
