Hardness of organic coatings is based on the amplitude of the oscillation of a rocking device that decreases more rapidly on a softer surface
Conforms to test procedure ASTM D 2134
Unit is set to obtain 50 oscillations on a standard glass plate representing 100%. Sample is compared to the glass plate standard as a percent of the standard. Number of oscillations is easily adjusted with knurled nuts on a vertical threaded rod. Dimensions: 500 x 340 x 300 mm; Weight: 1.825 kg. Includes draft-proof plastic hood and leveling table.
