Any viscometer experts on here? I was watching the tv show "how its made" and have seen this device 2-3 times at different factories, the last I think was in a paint, or crayon factory. The test batch guy would take a sample of the mixture,put a glob on a metal scale and wipe a straight edge across it, then he would measure how far down the scale the mixture went.. If it went the correct length the batch was ok to run and he passed the sample.. Do any of you know what this type of measuring device is called? I searched viscometer and all I came up with is digital ones that spin. thanks!
