Thermal Disinfection Indicators

Thermal Disinfection Indicators (TDI) are adhesive labels that are used to identify if the surface of objects that have been cleaned in a dishwasher have reached a temperature high enough that they are sanitised.

As part of a thorough Food Safety and HACCP plan, these TDIs verify that disinfection has occurred and provide a record as part of good public health and food safety procedure.

To use the TDI labels, stick one to an item going into the centre of the dishwasher, such as a plate.

Once the dishwasher has run its cycle, read the label. The indicated temperature will have changed from silver to black. Remove the label whilst still warm and attach to a record for verification. The TDI can also be used in medical applications including laundry services. Simply place a TDI inside a small snap-lock bag and throw it in the wash cycle – easy!

The labels are non-toxic, water resistant and accurate to ±1°C
