Equipment Type: Low Resistance
The UT572 is a ground resistance test kit that verifies grounding systems using 2-, 3-, and 4-wire earth-resistance methods and adds soil-resistivity measurement, so the same kit checks an existing electrode and surveys ground for a new one. It is rated CAT III 600 V.
It measures across five ranges from 4 Ω to 40 kΩ, with dual test frequencies (94 Hz / 128 Hz) and disturbance-voltage handling to keep readings stable on live sites. Soil resistivity is measured over 1 m to 40 m electrode spacing, and 20 result groups store on-board. The kit runs on AA batteries for field portability.
It suits electrical contractors, utilities, and telecom and lightning-protection work involving grounding verification and soil surveys.
