Soil Resistance and Resistivity Measurement - Tellurometer
My 3123
Highly portable and powerful equipment for measuring both resistivity (Ω/m) and grounding resistance by different methods. With the two optional clamps it is possible to measure without the need to drive electrodes and also to measure leakage current or load current.
Advantages and characteristics:
- High portability
- Excellent price/performance ratio
- CAT IV
- 20m cables
- Measurement by various methods, 4-wire, 3-wire and non-electric
- Direct resistivity measurement
- Integrated help function
- USB port
- Commercial-size rechargeable batteries, integrated charger
My 3288
The MI 3288 ground insulation tester is a portable, battery-powered test instrument. It has excellent IP protection and is designed for use at high altitudes (300 V CAT III at 4000 m). It is intended for the measurement of ground resistance, resistivity, ground potential, touch and step voltage, insulation resistance and continuity of protective conductors of various devices, whether energized or de-energized. The MI 3288 earth insulation tester also supports 4-wire earth resistance measurement method in combination with one clamp, 2-clamp earth resistance measurement, 4-wire resistivity measurement and TRMS current measurement.
