60A to 1000A AC Load Current Clamp Meter with 45Hz to 400Hz bandwidth in innovative flip design Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3291-50 features a thin and compact clamp core that can measure load current between a wide 60 to 1000A range. The clamp meter is constructed so that the position of the display panel can be adjusted to suit the measuring location, and the back light makes it easy to use even in dark locations.

Lightweight Ground Clamps with Bluetooth® Data Transfer The FT6380 and FT6381 measure grounding resistance simply by clamping to multiple-grounded ground wires. No auxiliary grounding rod is needed, and there is no need to disconnect the ground wire from the grounding rod. The compact, low-profile sensor can be used to clamp ground wires with ease, and also provide AC current measurement functionality and can measure currents ranging from leakage current on the order of several mA to load currents of up to 60 A. Note) The application supports Android™ OS 2.1 or later, but proper operation is not guaranteed on all Android™ handsets. For more information about the devices on which proper operation has been confirmed, please refer to the notes on the right. Please download and install the “FT6381 Communication Software” from the Google Play™ store in order to use the wireless connection function with an Android™ phone. The software is free, but the user is responsible for any Internet connection costs incurred in the course of downloading or using the application.
