Datasheet

This device its commonly use to verify the freshness of milk and to detect sub-clinical mastitis in the cattle.

The functioning its simple:

  • Collecting a sample of milk.
  • Perform the test by pulsing the test button.
  • Check a paper printed reference table of values and possible correlations.
  • Determine a diagnostic based in the lecture.
