Description

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.

Key Features
• Ideal for use in environmental testing with broad -40˚C to 85˚C temperature range
• High precision with a clamp-type design, ±0.3% amplitude accuracy, ±0.1° phase accuracy
• Wide-bandwidth DC to 1 MHz
• Single-handed operation and robust locking mechanism
• Reduced effects from magnetic fields, conductor position, and noise from nearby wires
• For EV/HEV battery charge and discharge efficiency measurement and inverter and power conditioner conversion efficiency evaluation

High-accuracy current sensors ideal for use with oscilloscopes and power meters

Compared to current sensors that use Hall elements, flux gate type current sensors are not prone to measurement error caused by variations in the external temperature. In addition, they can measure extremely low input (current values) and current waveforms with phase that lags by 90° with a high degree of precision. The CT6840 Series AC/DC Current Probes are ideal for measuring power waveforms with a digital oscilloscope and power meters.

Ideal for thermostatic chambers and engine rooms

The CT6841 series is ideal for operational evaluations of devices inside equipment that is subject to extreme temperature changes, offering tough, high-precision testing thanks to its broad temperature characteristics and an operating temperature range of -40°C to 85°C. The clamp sensor's tough performance helps ensure you can make the measurements you need.

Measure the charge and discharge efficiency of EV/ HEV batteries

In many situations, it is not possible to use high-accuracy pass-through sensors to evaluate EVs and HEVs since their wiring cannot be easily disconnected. The CT6841’s clamp-type design and resin casing make them more resistant to deformation from heat than that used in legacy products, allowing you to take measurements under the hood with extremely high precision.
