A Metravi Pro Soil Resistivity Tester is a device for measuring the resistance of soil, used for applications like ground resistance testing and grounding system design. Models like the ERT-1602 use precision 2, 3, or 4-wire methods for measurement, including the Wenner method for soil resistivity. The ERT-1635 is a double clamp tester designed for similar on-site measurements, which can also measure ground voltage and current. 

UT582+ is mainly used to detect whether the RCD in the circuit can be triggered normally. It is only suitable for single-phase circuits with the supply voltage range of 195V~253V. Its voltage measurement range is 30V~600V, 45Hz ~65Hz.
