The BRK CTN-210B is a professional-grade coating thickness gauge designed for precise, non-destructive measurement of coating layers on both ferrous and non-ferrous substrates.
All BRK meters and probes ship direct from the manufacturer and require 10-15 business days for shipping.
Utilizing magnetic induction and eddy current measurement principles, it delivers accurate thickness readings for a wide range of coating types, including paint, plating, powder coatings, anodized layers and protective films.
Built with a rugged metal housing and user-friendly interface, the CTN-210B is suitable for demanding industrial environments. Its interchangeable probes and dual measurement modes make it ideal for automotive, marine, manufacturing and quality control applications where reliable coating assessment is critical.
-
Dual Measurement Technologies
