Multi-layer Film Thickness Measurement

PELT technology leverages ultrasound to measure Pulse Echo Layer Thickness, setting a global standard for high-resolution, multi-layer precision thickness measurements. PELT is a non-destructive, high-resolution instrument, enabling precise paint process control by measuring every layer individually and simultaneously.

Paint and Coating Layer Thickness is a Critical Measurement

Measurement Applications

Multiple layers of coatings on automotive steel and aluminum body panels.
Automotive plastic bumpers and other automotive trim components.
Primer and topcoat systems for construction equipment, railroad locomotives and rolling stock, and high-speed railway equipment.
Wind turbine blade coatings, shipping container anti-corrosion and topcoat coatings, and marine coatings.
Paint coatings and lacquers on wood such as cabinetry, furniture, musical instruments, and flooring.
Laminate coatings and layers.
