The detector measures changes in the electrical resistance of milk, as development of sub-clinical mastitis (asymptomatic stage) is accompanied by an increase in salt levels in milk, which involves a change in the resistance. This rule is considered to be the most reliable indirect test in diagnosing subclinical Mastitis .

- you need to milk the first portion of milk directly from the teat to measuring cup
- press the button to register the result
- pour out the milk and repeat the steps for other quarters.
