This motorised apparatus is dedicated to coatings hardness evaluation based on scratching resistance method. A test panel is clamped and slowly moved whilst a stylus or alternative tool scratches the surface. Depending on test procedures, specified or variable loads can be applied to obtain different degrees of failure, from trace to destruction. A voltmeter indicates the contact of the tool with the metallic sample substrate. Max. panel size : 100x150x1.6mm (0.3mm coating). Alternatively a simple manually operated version is also available.
- Robust construction, reliable and reproducible results
- Simple maintenance, easy to replace tools
- 220-240V / 50Hz (110-120V / 60Hz on request, please specify)
Specifications allow for use of either the (preferred) mechanised or hand operated apparatus. A test panel is clamped to a slide which slowly withdraws the panel while a needle scratches the surface. Tests are conducted either on a ‘go/no go’ basis using a single specified load or by increasing the load to determine the minimum load at which the coating is penetrated.
