The TQC Karsten Tube Penetration Test is a simple test for measuring the degree or water penetration into building materials such as concrete, stone and plaster. The test consists or a glass tube filled with water, bonded to the test material with plastiline. Water pressure is then exerted on the surface. A graduated scale indicates, over time, the amount or water penetrated into the surface.
- Tube Material: Glass, 0-4mL in 1/10th mL graduations
- Used for the detection of coating porosity (pin-holes, or holidays) in dielectric (insulation type) coatings on conductive substrates, includingconcrete
- Additional vertical or horizontal tubes are available on request.
- Always clean the instrument after use and keep it in its case when
not in use.
