This thermo label is based on a reversible thermo sheet and combines an irreversible temperature indicating element in the center.
The temperature indicator element shows the past temperature history, and the current temperature is displayed by the presence or absence of discoloration of the base (the left side changes color at 70°C, the right side at 50°C). Size: Base part/15 x 30 mm, temperature indicator element part/6 x 12 mm
Quantity: 1 box (80 sheets)
Discoloration temperature: 65℃ (temperature indicator element)
Primary color → Color change: White → Black (Thermoelectric element)
Irreversibility/Reversibility
Discoloration temperature: Left side/70℃, Right side/50℃ (base)
Primary color → Discoloration: Left side/red →← dark brown, Right side/yellow →← yellowish orange (base part)
*The color change from high temperature to low temperature due to a drop in temperature is approximately 15°C lower than the displayed temperature due to the hysteresis phenomenon.
