N3A hardness tester
HIGH EFFICIENCY AT LOW COSTSThe N3A tester in detail
High efficiency at low costs: The N3A tester offers individual, easy-to-handle test loads thanks to a reliable, vibration-insensitive spring-loaded system. Several test units with variable loads guarantee precise measurements. The values are displayed on a robust, analogue dial gauge.

Analogue dial gauge clearly displays the result.
Simple test piece infeed with handwheel.
Interchangeable spring sleeve for different test forces.

Very simple handling
The load is applied with a 180° pivoting hand lever.
(pre-load and main load stage).
1. Application of preload
2. Application of main load
3. Application of second preload
4. Back to starting position

Replaceable spring sleeve system
The N1A test unit with replaceable spring sleeves is used for different load levels. The spring bushings are available in different versions for different load levels.
