Tru-Test - Electronic Milk Meter (EMM) Calibration Rig

During milking of each cow the Tru-Test EMM separates a known and accurate portion of the cow`s milk and collects that small portion of milk in the flask. The Milk Meter then measures how much milk is held in the flask by measuring the height to which milk has collected in the flask. Each Milk Meter is programmed with a calibration curve, which is used to convert height of milk in the flask to a known volume in the flask.
