The TQC hardness test pen is a pocket instrument from Paul Gardner Co. designed for testing the hardness and wear/scratch resistance of materials such as coatings, lacquers, plastics or related products. A tungsten carbide tip is drawn over the surface with a defined constant pressure. The pressure on the tip can be changed using the slide or by changing the spring. A visual mark on the surface after use of the pen indicates a fail of the surface hardness or wear/scratch resistance. Available in two models, basic and pro, the pen is suitable for testing paints, coatings and varnishes in a variety of industries.
