Barrels

Barrels of the PTR HARTMANN Test Probes are made of bronze, brass or nickel silver. They are manufactured by either deep-drawing or milling tubing or solid rods. A gold coating ensures excellent contacting characteristics.

A barrier layer provides very good protection against corrosion. The barrel protects the moving parts. At the same time, small tolerances ensure precise plunger guidance.
