Measure the viscosity of liquids such as paint, lacquer, oil, and syrups. Simply insert the cup into your sample and lift the viscosity cup out, starting a stopwatch/timer. Cup is made of series 400 stainless steel and requires 44 mL of sample for the test. After withdrawing the cup, measure the time it takes until the first break in the liquid stream. A conversion sheet is supplied that will convert the Zahn time to a centistokes value. Simple and convenient – no complicated training needed.
