Use: Cleaning surfaces

Description: Can remove rust, paint and or other objects from surfaces.

Electronic Equipment


Use: Used for measuring information in a circuit and for diagnosing circuit problems.

Description: Measures various information in a circuit, including voltage, current (amperage), and resistance.

DC Current Clamp Meter

Use: Used to test current in a circuit and for diagnosing current problems in a circuit.

Description: Measures current (amperage) flowing through a wire by clamping device around a wire and measuring the magnetic field given by said wire.

Hand Tools


Ball Peen Hammer

Use: Used in metalworking.

Description: Has a ball-shaped backside used to flatten and or bend metal.

Claw Hammer
