The Newtonian viscosity cup is used to test or similar Newtonian fluid viscosity. In workshops, factories and laboratories used anywhere for quick check and adjust a variety of different fluid viscosity. Should be selected before using the appropriate number of cups in order to control the outflow of time between 10 to 90 seconds. Note: Use when you need a relatively high precision stopwatch.
Every zahn cup has a 12inches annular holder,hold it until the cup immerges the liquid.And there is a ring on the middle of the holder,it is for keeping vertical when immerging.When the liquid is over the cup,lift the ring ,pull vertically,until the cup already out of the liquid,press the second watch at the same time.You can see the liquid flows out of the cup through the small hole which at the bottom of it .Until all the liquid is out of the cup,stop the second watch at the same time.Then the reading on the second watch,is the viscosity value of the liquid.
Role: an accurate measurement of ink viscosity, precise color matching
