Stainless steel probe pierces insulation on 14, 16 and 18 gauge wire. You control needle depth to minimize insulation damage. Essential for use under hood or under dash. Use it on fuel injectors or sensors while providing complete insulation to grounding due to design. The TP81 connects to banana jack leads (such as Fluke’s TL224).

• Banana jack accepts all DMM and banana jack leads
• Non-rotating banana jack prevents leads from tangling, allowing you to tighten/loosen clamp while still connected to the test lead
• For use with test leads with 4 mm banana plugs
• Tested to 60 V DC
