IEC60335‑1 Tracking Resistance Tester for Appliance Insulation Performance Test

IEC60335‑1 Tracking Resistance Tester for Appliance Insulation Performance Test

Product information:

The SN774 Comparative Tracking Index (CTI) and Proof Tracking Index (PTI) tester is a professional laboratory testing device engineered for evaluating the tracking resistance performance of solid insulating materials. Fully compliant with global IEC, UL and ASTM international standards, this precision testing equipment is widely adopted by quality inspection laboratories, manufacturing factories and third-party certification institutions across Europe, North America, Southeast Asia and other global regions.

Simulating the actual working environment of electrical products, the tester adopts ammonium chloride liquid dripping and high-voltage electrode conduction mode to detect insulation failure, tracking breakdown and flame ignition of insulating materials under the combined action of electric field, humidity and contaminants. It provides accurate and reliable test data for material selection, product safety certification and quality control of electrical and electronic products.
