VKCR3250 Pylon Earth Resistance Tester

1. 4-clamp method measure the pylon earth resistance , which is no need to trip the pylon and grounding network, fast and safe, time-savingandlabor-saving.

2. Use 2/3/4-wire method measure the earth resistance & soil resistivity, and the tester also can measure earth voltage and AC leakage current. Theclamp current sensors can be used as clamp ammeter.

3. The host equip with 7-inch large colorful screen, built-in printer and large-capacity rechargeable lithium battery pack, packing with waterproof case. Andthe Bluetooth communication is especially suitable for outdoor construction sites.
