6V DC Clamp Type Digital Earth Resistance Tester 30A 1300Ω 32mm
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.
