HACCP Check
Green LED backlighting
Green LED backlighting indicates safe cooling or frozen state
below 4°C (40°F) or a safe holding temperature above 60°C
(140°F).
Red LED backlighting
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 flashes when measuring with the probe
sensor.
100°C
Above 60°C: Hot food zone
Bacteria are killed by heat above 60°C.
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.
4°C
Below 0°C: Freeze zone
0°C
No bacterial growth below -18°C
