Babcock Milk Tester

video

Though a little shaky, the above video provides a good idea of a hand-worked Babcock Milk Tester in motion. The tester is in the collection of the Bega Pioneers Museum, who have kindly allowed me to present this material.

As per the last post, the centrifugal machine was worked by the user rapidly rotating the hand crank for about half a minute. This machine could fit two samples at any one time.
