TH8058B High Voltage Tracking Index Tester/High Voltage Tracking Tester

Purpose
This instrument is suitable for testing electrical and electronic products, household appliances and their materials for tracking resistance and corrosion resistance. It simulates the use of liquid contaminants and inclined samples at power frequency (48Hz-62Hz) to pass the tracking resistance test. And corrosion measurement to evaluate the resistance to tracking and corrosion of electrical insulating materials used under severe environmental conditions. This machine is designed and manufactured in strict accordance with GB/T6553-2003 and IEC60587-1984.
