Soil Resistance and Resistivity Measurement - Tellurometer
My 3123
A highly portable, high-performance device for measuring both resistivity (Ω/m) and ground resistance using various methods. With the two optional clamps, it is possible to take measurements without having to drive in electrodes, as well as to measure leakage or load current.
Advantages and characteristics:
- High portability
- Excellent value for the price
- CAT IV
- 20-meter cables
- Measurement using various methods: 4-wire, 3-wire, and electrode-free
- Direct measurement of resistivity
- Built-in Help Feature
- USB port
- Commercial-size rechargeable batteries, built-in charger
My 3288
The MI 3288 Ground Insulation Tester is a portable, battery-powered test instrument. It features excellent IP protection and is designed for use at high altitudes (300 V CAT III at 4,000 m). It is intended for measuring earth resistance, resistivity, earth potential, step and touch voltages, insulation resistance, and continuity of protective conductors in various devices, whether energized or de-energized. The MI 3288 Ground Insulation Tester also supports the 4-wire ground resistance measurement method in combination with a clamp, ground resistance measurement with two clamps, 4-wire resistivity measurement, and TRMS current measurement.
