Description
Overview
GAOTek’s portable hardness tester for metals, coatings, and weld seams is designed for easy operation with a large LCD display that shows all relevant information. Hardness scales and materials can be quickly adjusted with special keys. Using the UCI (Ultrasonic Contact Impedance) measuring method, it provides fast and accurate measurements, regardless of direction. The measured value appears immediately after the test load is applied. It offers versatility for various applications and sample surfaces.
Features
- Low power consumption
- Fast and easy hardness testing
- Robust metal casing
- Large color display
- Built-in Lithium-Ion battery
- Extensive storage and statistical functions
- USB-C interface for data transfer to PC and USB flash drive
