Portable UCI Hardness Tester for Accurate Metal Testing

The Sauter HO is a professional ultrasonic contact impedance (UCI) hardness tester designed for fast, non-destructive testing of fine-grained metals, welded seams, small components, and gear teeth. Offering selectable test forces from 1 kgf to 10 kgf, it provides precision measurements across a variety of industrial applications. Built-in memory, real-time statistics, and USB connectivity make it a versatile and user-friendly solution.

Compliant with DIN 50159-1 and ASTM A1038 standards, the HO series combines portability with reliable, laboratory-grade performance—all within a compact and robust instrument.
