Hardness Testing Pencil
Description:
This pocket instrument allows hardness tests on flat and curved surfaces. The instrument consists of a sleeve with a pressure spring that can be bent to various tensions by using a slide.
The spring acts on a tungsten carbide needle with its tip extending out of the sleeve. A locking screw fixes the slide, thus maintaining constant spring tension.
Three pressure springs of varying strengths ranging from 0-20 N (0-2000 g) are available to cover a large hardness range.
