A Porosity Tester is a specialized device designed to detect pores, pinholes, cracks, and other discontinuities in non-conductive coatings applied over conductive substrates such as steel or concrete. It ensures the integrity of protective coatings by identifying defects that may compromise corrosion protection or structural performance. Depending on the model, porosity testers use low-voltage (wet sponge method) or high-voltage (spark testing) techniques to perform inspections on coatings of varying thicknesses.

Ideal for use in industries such as oil & gas, marine, construction, and pipeline maintenance, porosity testers are crucial for quality control in coating applications.

• Multiple Testing Modes: Available in low-voltage (wet sponge) and high-voltage (spark test) variants to suit different coating thicknesses.

• Adjustable Voltage Range: High-voltage models allow adjustment for coatings up to several millimeters thick.

• Visual and Audible Alarms: Immediate notification when a defect is detected.

• Compliance: Conforms to international standards such as ASTM D5162, NACE SP0188, and ISO 29601.

• Portable Design: Lightweight and ergonomic for field or lab use.

• Battery Operated: Rechargeable or replaceable batteries for flexible operation in remote areas.

• Data Logging (Optional): Some models include memory storage for test results.

• Pipeline Inspection: Checking coating integrity on buried or submerged pipelines.

• Tank and Vessel Linings: Ensuring internal coatings are defect-free to prevent corrosion.

• Marine Structures: Testing ship hulls and offshore platforms for coating breaches.

• Bridges and Infrastructure: Verifying the quality of protective coatings on steel structures.

• Industrial Coatings: Quality assurance in painting and powder coating applications.
