Name: K5-C – Electromagnetic Coating Thickness Gauge
Brand: NDT1 KRAFT

Description

The K5-C is a multifunctional portable coating thickness gauge designed for routine and advanced non-destructive inspection of protective coatings on ferrous and non-ferrous substrates. With interchangeable magneto-inductive, eddy-current and phase-sensitive eddy-current probes, the instrument can be configured for measuring paint, lacquer, powder, enamel, galvanic and other metallic or dielectric coatings over a wide thickness range.

The modular probe system extends the K5-C beyond conventional coating thickness measurement. Depending on the selected probe, it can be used for internal pipe coatings, thick protective layers, concrete cover and reinforcement location, wall thickness of fiberglass and carbon-fiber structures, surface profile assessment and environmental monitoring during coating application.

The K5-C is suitable for production control, incoming inspection, coating application and field maintenance. Measurement data can be stored in groups and transferred to a PC via USB for further processing and documentation.
