Consistent, high-precision current testing across a wide temperature range
These Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory Recorders and high-performance oscilloscopes. The CT6841 and CT6843 are DC to 1MHz/20A and DC to 500kHz/200A sensors, ideal for capturing signals during the efficiency testing of batteries, inverters and power conditioners.

The CT6841 and CT6843 have an operating temperature range of -40°C to 85°C making them ideal for measuring the charge and discharge efficiency of EV/HEV batteries, evaluating inverter and power conditioner efficiency, and evaluating fuel cells, contact-less power supply circuity, and other next generation devices.
The CT6841 and CT6843 cannot be used alone. The optional 9555-10 is required in order to supply power and connect the clamp to a Memory Recorder or other instrument. These clamp meters can however, can be directly connected the 3193-10 and 3390 Power Meters.
Included: Instruction manual, six (6) mark bands, and carrying case.
