The LED backlighting is red when the measured temperature
is between 4°C and 60°C. The product temperature is in the
HACCP danger zone.
The backlighting ashes when measuring with the probe
sensor.
Above 60°C: Hot food zone
Bacteria are killed by heat above 60°C.
4°C … 60°C: Danger zone
Bacteria grow rapidly between 4°C and 60°C.
0°C … 4°C: Cool zone
Bacteria grow very slowly between 0°C and 4°C.
Below 0°C: Freeze zone
No bacterial growth below -18°C
