ThermoTrace Time Temperature Indicator labels

DeltaTrak's cold chain solution includes the ThermoTrace TTI labels and the ThermoTrace TTI Service. These time temperature indicator labels are low cost single-use barcode labels that support a variety of pre-set time and temperature events. Based on a proven (non-toxic) chemical process, this temperature indicator label changes the barcode as it tracks up to three levels of cumulative temperature abuse above the threshold temperature stated on the label. This dynamic process is captured in real time with every scan done by a barcode reader.

Customers who purchase these temperature indicator labels but do not subscribe to the ThermoTrace TTI Service will only receive pre-configured feedback messages on the scanner. They will not receive any alert messages by email or SMS text.

DeltaTrak currently offers two temperature indicator label models. These models are part number 55100 with a 32°F (0°C) temperature threshold limit and part number 55101 with a 41°F (5°C) temperature threshold limit. The labels are designed to change the valid barcode reading when the product has reached separate events. There is only one valid barcode at any point in time. When scanning a ThermoTrace temperature indicator label, the first row of barcode is readable only if the label has not been activated, this is known as Quality Code Event 1. The second row of barcode is readable when the label has been activated and there has been no temperature exposure above the stated threshold of that particular label, and this is known as Quality Code Event 2. The third row of barcode is readable when a certain amount of accumulated time above threshold has occurred. For example, the 32°F TTI Label will have a reading in the third row as soon as the label has been exposed to 32°F, and the 41°F TTI label will have a reading in the third row as soon as the label has been exposed to 41°F. This is known as Quality Code Event 3. The fourth row of barcode is readable when the label has reached a second level of temperature abuse. For the 32°F TTI Label this will register when the label has been exposed to an accumulated time of 4 hours above 32°F, and for the 41°F TTI Label this will be when the label has been exposed to an accumulated time of 4 hours above 41°F. This is known as Quality Code Event 4.

The 32°F time temperature label would typically be used for frozen commodities such as meat, seafood or chicken that requires lower temperatures. The 41°F time temperature label would typically be used for commodities such as produce, chemicals or pharmaceuticals that can tolerate a slightly higher temperature.
