Elcometer 260 UV Pinhole Flashlight

The Elcometer 260 UV Pinhole Flashlight is battery powered and housed in a rugged aluminium case providing  a quick, low cost method of testing coatings for pinholes.

Featuring a three-Watt purple light emitting diode, the Elcometer 260 UV flashlight has a beam wavelength of 405nm (±5nm), which the human eye perceives as a purple light.

Designed with a specialised diffuser lens that emits a smooth beam image (with no streaks, hot spots or dark spots) and used with National Surface Treatment Centre approved safety glasses for improved contrast, the Elcometer 260 UV flashlight provides optimum integrity and reliability of the visual inspection.

The Elcometer 260 UV flashlight can detect pinholes from both the base and top coats. A UV reflective additive is applied to the base coat. When inspecting the fluorescent base coat look for black spots or grey areas that indicate pinholes. When inspecting the non-fluorescent top coat, look for glowing spots that indicate pinholes in the top coat (shining through from the base coat).

  • Low cost and easy to use: Use UV reflecting base coat and shine the purple light onto the surface. Any fluorescence identifies pinholes
  • Rugged: Manufactured from aluminium alloy and O’ring sealed to protect it from moisture and dust
  • Portable and secure: Battery powered and features a recessed click-on/push off button to prevent accidental activation during transport or storage.

An Introduction to Pinholes and Holidays – Porosity Detection

Corrosion is caused by two things – a steel substrate and oxygen, while contaminants such as water can accelerate the process. The coating is there to protect the steel from oxygen and contaminants. A flaw in the coating can leave the substrate poorly protected, or in some cases completely exposed.
