The original non stick Teflon probe was designed by MIRINZ to be used on the surface of chilled meat to calculate PHI ( Process Hygiene index ) values. Process Hygiene index values are calculated and displayed in the statistical section of Temprecord for Windows software.
A detailed explanation on how to apply PHI values is given on pages 40 to 45 in the Temprecord for Windows user manual and also in the help file of Temprecord for Windows software.
