6V DC Clamp Type Digital Earth Resistance Tester 30A 1300Ω 32mm
VICTOR 6412 Clamp Ground Resistance Tester 30A 1300Ω Clamp Open Size 32mm
Clamp-on ground resistance tester is a major breakthrough in traditional grounding resistance measurement. It is widely used in the grounding resistance measurement of the power,
telecommunications,meteorology, oilfield, construction and the industrial and electrical equipment.
Clamp-on ground resistance tester, in the measurement of a grounding system with loop, does not require breaking down the grounding wire, and need no auxiliary electrode. It is safe, fast and simple. Clamp-on ground resistance tester is equipped with a long jaw sized65mm×32mm, particularly suitable for the grounding with the flat steel. Besides, can measure leakage current and zero-sequence current with sensitive clamp. It is significant when there is noise signals and harmonic waves in grounding network to measure.
