Puncture Tester: Measures the puncture strength of materials like rubber or plastic film by recording pressure levels at penetration.
Insulation Tester: Measures insulation resistance (IR) of materials, identifying faults to prevent current leakage and hazards.
Both testers help ensure the safe operation of systems by identifying flaws in equipment.
Regular testing is advised to monitor insulation decay, especially in rough environments.
