Fluke 1625 Advanced Soil Conductivity Meter

The Fluke 1625 is the advanced earth ground tester that performs all four types of earth ground tests and includes features that give quicker and more accurate readings.

Testing Methods

• 3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
• Selective testing – without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp.
• Stakeless testing – innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance

The Fluke 1625 offers these advanced features

• Automatic Frequency Control (AFC) – identifies existing interference and chooses a measurement frequency to minimize its effect, providing a more accurate earth ground value.
• R* measurement – calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see.
• Adjustable limits – for quick test result verification.
