Gardco says its new app can calculate the kinematic viscosity or drain time of Gardco and BYK viscosity cups quickly and easily. Input the drain time or viscosity into one of the given input fields and then select the viscosity cup type to calculate the viscosity or drain time of a sample. If the selected cup is highlighted in green, it is within the cup’s viscosity range and the number is valid. If the sample is outside of the cup’s range, an error message will appear. Switch to a different cup in range for what you would like to test. Determine which cups are in range for your desired value by inputting the value you want to test and scrolling through the list. Any cup in green will provide a valid measurement for the desired input. Choose from 52 viscosity cups. The app is a free download for Android or Apple smartphones, or download the desktop version.
