Mas-D-Tec measures the levels of sodium and chloride in the milk. These are increased by bacterial infections. As levels rise, milk quality is lower and production will be reduced. 

• A small sample of quarter milk is squirted into the funnel top.
• Within two seconds the milk conductivity is analysed and indicated on the graphic scale.
• The milk drains through the Mas-D-Tec as the readings are taken.
• There is no need to tip the milk out. Simply continue to the next quarter and add more milk.
• The instrument detects the new sample and provides a new reading. 
• There is no need to wash the Mas-D-Tec between quarters and cows. Washing at the end of milking is all that is required.
• Mas-D-Tec is so fast to use that it is possible to test the whole herd during milking.
