The Automotive Wire Hot Water (Salt Water) Resistance Tester is engineered for long-term (over 14 days) testing of automotive and locomotive wires under DC voltage and salt water immersion conditions. This system evaluates insulation resistance, voltage endurance, and corrosion resistance of wires exposed to hot water and saline environments. It ensures the durability and safety of wiring systems in automotive and industrial applications.
Application
The tester is primarily used in the following applications:
Automotive primary wires and battery cables
Locomotive and industrial control wires
Connector and harness testing under hot water or saline immersion
Long-term durability assessment under DC voltage and corrosive environments
Verification of automotive wiring harnesses exposed to heat, water, or saline conditions
