Hioki FT6380 Clamp On Earth Tester

Hioki Launches Clamp On Earth Tester for Multiple Grounding Use Convenient, Low-profile Sensor is Ideal for Confined Locations FT6380 / FT6381

HIOKI E.E. CORPORATION is pleased to announce the launch of the FT6380 Clamp On Earth Tester for multiple grounding use and the FT6381 featuring Bluetooth® wireless technology. The two products were developed specifically to meet the needs of customers in North America, Europe, and Asia, where there is high demand for multiple grounding measurements.

Thanks to the small size of the clamp sensor, the FT6380 and FT6381 deliver a new level of convenience especially when used in confined locations. At the same time, we have increased the size of the grip used to open the sensor, allowing the new meters to be operated with only half the force required for similar products offered by other companies. Finally, the FT6381’s incorporation of Bluetooth® wireless technology allows it to be linked to Android™ handsets for report creation.

Need for Grounding Resistance Measurement

“Grounding” generally refers to the act of connecting an electrical device with the ground (earth) in order to zero out any potential difference. Electrical equipment must be grounded for safety reasons because ungrounded devices (that is, devices with a non-zero potential difference) may cause electric shock if they malfunction or suffer degraded components.

Utilities and service contractors need to measure grounding resistance in order to verify whether a given device has been reliably grounded. While grounding ideally eliminates any potential difference, a potential difference does in fact occur between the grounded device and the earth. This fact signals the existence of a not negligible level of resistance, which is known as grounding resistance. It is absolutely critical that we measure grounding resistance in order to ascertain whether it has been minimized to ensure optimal safety.

Easy clamping!

Open jaws easily with just two fingers. Only half the grip power is needed compared to typical clamp earth testers.

Clamp at the narrowest point!

Now you can easily clamp the earth cable on the pole without digging. The dramatically slim 0.79 inch (20mm) jaws let you finish your job easily and efficiently.
