1. Use:

DC spark testing machine is the ideal equipment for all kinds of cable diameter 10mm below surface damage and spark detection, it uses the internationally recommended form of DC voltage, its advanced design, novel structure, has stable output voltage, high detection sensitivity, adapt to the characteristics of good, easy to use, flexible installation, safe and reliable. It can and online detection of stranding machine, extrusion machine and other ancillary equipment, can also be used for detection of intermediate products and factory inspection. With GB/T3018.15, JB/T4728.10 and BS5099 standard, inspection sensitivity is less than or equal to 600uA, stable performance, beautiful and durable.
