I would like to hear from those that have done any viscosity testing.
Below is the definition of the SUS method, which I have seen quoted in technical articles.

I am looking at used viscosity equipment, but thought that some of you may have devised some simple DIY, at home use, methods for viscosity.

I would think that some of the important parameters would be:

1. temperature - being able to test at different temps. Equipment to take fluids to needed temps.
2. graduated containers - lab supply store pipettes or other cylinders.
3. A container with a hole that has a known flow rate at a given viscosity, or ability to determine the flow rate for testing.
4. Stop watch.

So, if I know the ambient temp, the temp of the fluid being tested, drop the measured quantity into the flow rate device, check the time = viscosity ?

SUS (SSU)—Saybolt Universal Seconds: The time, in seconds, for 60 ml of fluid to flow through a capillary tube in a Saybolt Universal viscosimeter at a given temperature. Usually measured at 100°F and 212°F. This term is being replaced by the centistoke, cSt.

I hope not to have endless links to heavily scientific journals with copius amounts of reading that tend to obfuscate the needed information.

Obfuscate: Def. To make so confused or opaque as to be difficult to perceive or understand.

Let's make this easy to read and understand.
