NDH-B high Voltage tracking testing instrument

NDH-B high Voltage tracking testing instrument

Product Overview:

Tracking test (electric mark index test) is in solid insulation material on the surface, in the specified size (2 mm x 5 mm) between the platinum electrode, applying a voltage and timing (30 s) high (35 mm) drop the conductive liquid droplet volume 0.1% (NH 4 CL), to evaluate solid insulation material surface under combined electric field and damp or pollution medium leakage resistance, compared to measure its electrical mark melt index (CT1) and electric mark the index (PT1). Tracking tester (electric mark index tester) instrument is suitable for lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motor, electric tools, electronic instruments, electrical instrumentation, information technology and equipment research, production and quality inspection departments, can also be applied to insulation materials, engineering plastics, electrical fittings, accessories industry.
