The PMA-1010 is a portable, nondestructive residual stress tester based on the indentation method. It measures residual stress in metal components without causing damage, making it ideal for in-situ evaluation of in-service equipment. With a maximum load of 1000 N and indentation depth of 60-120 μm, it provides macro-scale stress data with minimal surface impact.
Product Summary
This tester offers a fast, accurate alternative to traditional hole-drilling methods. It is designed for field use in demanding environments like chemical plants, pipelines, and pressure vessels. It supports common metals including steel, aluminum, titanium, and nickel alloys.
Key Features
Non-destructive – Leaves tiny indentations that do not affect serviceability of valuable parts.
Fast results – Faster than hole-drilling and leaves minimal surface damage.
Versatile – Insensitive to microstructure, suitable for various metals.
Convenient – Requires no couplant, eliminating surface contamination and cleaning steps.
Precise – Pinpoints micron-sized areas for accurate local property measurement.
Clear output – Automatically distinguishes tensile and compressive stress.
