TQC Hardness Test SP0010 is a pocket-sized instrument for testing the hardness and abrasion/scratch resistance of materials such as paints, varnishes, plastics or related products. Draw a tungsten carbide tip on the surface with a defined constant pressure. The pressure on the tip can be changed by a slide or by changing the spring. Visible markings on the surface after using the TQC hardness test SP0010 indicate failure in surface hardness or abrasion/scratch resistance. Can be used on flat and curved surfaces.
test preparation
1. Make sure the correct tip is installed and the correct spring is placed
2. Adjust the scale to the color that belongs to that spring
operation method
1. Release the red knob on the slider and set the slider to the desired position, then turn the red knob clockwise to fix it. (Note that the slanted edge of the slider indicates the correct position).
2. Place the Tester vertically on the surface to be tested, and press the holder firmly and lightly to create a load on the tip.
3. Move the Tester about 10mm on the surface within 1 second .
4. Observe the surface to check for visible marks.
