Fluke 1625-2 Advanced GEO Earth Ground Tester
The Fluke 1625-2 Advanced GEO earth ground tester features automatic frequency control for interference-free measurements, 1500-record internal memory with USB transfer, and an IP56-rated rugged case for all-weather field testing.Overview
The Fluke 1625-2 Advanced GEO Earth Ground Tester simplifies and accelerates ground resistance testing with its Automatic Frequency Control (AFC), which scans for site interference and selects the optimal measurement frequency automatically. The instrument also provides an R* measurement function that calculates earth ground impedance at 55 Hz — more accurately representing the resistance a fault-to-earth event would encounter. Combined with 1500-record internal memory, a USB data port, colour-coded wire leads, and new quick-reel accessories that cut setup time by up to 50%, the 1625-2 is built for speed and accuracy in demanding outdoor environments.
Key Features
- Automatic Frequency Control (AFC) identifies and minimises the effect of site interference for more accurate ground resistance values
- R* measurement calculates earth impedance at 55 Hz to reflect real fault-to-earth conditions

- 3-pole and 4-pole Fall-of-Potential, and earth resistance loop testing
- 4-pole Soil Resistivity testing for site characterisation
- Selective earth ground rod testing using one clamp
- Stakeless earth ground testing using two clamps — no stakes required
- Adjustable test limits for faster pass/fail field verification
- Heavy-duty stakes and colour-coded wire reels included; setup time reduced by up to 50%
- IP56-rated housing for all-weather outdoor use

Frequently Asked Questions
What are the main methods for measuring earth ground resistance?
Fall-of-Potential (3-pole and 4-pole) and stakeless clamp methods are standard; each suits different site conditions and accessibility constraints.
When is soil resistivity testing needed?
Soil resistivity testing helps design grounding systems for new installations by characterizing earth conductivity at different depths.
Can this tester work in confined or hard-to-access locations?
Models with clamp or compact designs can access tight spaces, while traditional stake-based methods work best in open areas with sufficient space for probe placement.
How does weather affect ground resistance measurements?
Soil moisture and temperature variations influence resistance values. Test during consistent conditions when possible, and monitor seasonal trends for accurate baseline comparisons.
Why is water-resistant design important for ground testing equipment?
IP56 ratings protect against dust and wet conditions, ensuring reliable operation during outdoor testing in varying GCC climates without equipment downtime.
What is the typical acceptable resistance value for industrial grounding systems?
Generally, less than 5 ohms is preferred for safety compliance, though specific values depend on local standards and facility type. Consult Procure.ae for regional guidelines.
