Thermal Labels

Temperature Indicator Labels are small, low cost temperature indicator or time/temperature labels used during shipping, storage or processing. Typical uses include monitoring the temperature of pharmaceuticals, chemicals and fresh produce during transportation. The labels change color if there is a temperature excursion outside the preset limits. 

DeltaTrak offers a variety of labels depending upon your need. Labels such as the WarmMark® Time-Temperature Indicator, High temperature thermal labels and the TempDot Time-Temperature labels will indicate if the temperature excursion exceeded a pre-set time.  The Freeze Check™ Temperature Indicator and ColdMark® Temperature Indicator are used in shipments to indicate a temperature excursion below 32°F (0°C).  Used in commercial dishwashers, the TempDot High Temp Thermal Label will indicate if the final rinse has reached the HACCP required temperature of 160°F (71°C).

Freeze Check temperature indicator
The Freeze Check™ Temperature Indicator, Model 54000, is used to indicate an out of range temperature below 32°F (0°C). If an out-of-range temperature is reached, the irreversible temperature indicator changes from clear to white and the check mark is no longer visible.
ColdMark temperature indicator

ColdMark® Temperature Indicator, Models 51001-51002: Available in either 32°F/0°C or 26°F/-3°C, these stick-on temperature indicator labels can be applied to a product, package, carton or master pack of items sensitive to extremely cold temperatures.

When exposed at or below its response temperature for approximately 60 minutes, the liquid in this irreversible temperature label will turn cloudy with streaks of violet. Once warmed up above the response temperature, the liquid changes irreversibly to a uniform violet color.

51013-51035 WarmMark time temperature label
WarmMark® Time-Temperature Indicator, Model 51013-51035, monitor temperature of products during shipping, storage or processing. Response temperatures available range from 0°F (-18°C) up to 99°F (37°C).

These self-adhesive labels apply directly to product, package, carton or master pack. When activated, irreversible color change occurs once response temperature is reached or exceeded. Red indicates if exposure was for a brief, moderate or prolonged period of time.

You can see at a glance if a temperature abuse has occurred, providing permanent records for quality assurance purposes.
51036 WarmMark Duo time temperature label
WarmMark® Duo Time-Temperature Indicator, Model 51036, is a single-use thermal label designed to monitor temperature of blood and blood products, vaccines, and other pharmaceuticals during storage, shipping and distribution. It responds at two temperature thresholds, and is used for products with a known stability curve and with identified expiration characteristics for a specific time/temperature combination.

This cost-effective, self-adhesive label can be applied directly to a product and easily fits inside temperature-controlled packaging. When activated, the indicator windows remains white unless the label is exposed to temperatures above 50°F/10°C, then an irreversible red color migrates progressively towards the three windows. If the temperature goes below threshold, the color stops advancing. The first three windows indicate accumulated time above threshold, when colored red they denote exposure up to 3 days, 8 days, and 14 days. The fourth window indicates brief high temperature excursions, and turns red if the temperature goes above 93°F/34°C for at least 30 minutes.

WarmMark Duo shows at a glance if temperature abuse has occurred and for how long, thus providing visual evidence for making immediate decisions on whether product safety, efficacy and quality have been jeopardized.
54125 TempDot Dishwasher
TempDot High Temperature Dishwasher Thermal Labels, Models 54125 and 54126, are designed for use in commercial dishwashers and warewashers to ensure that the recommended sanitization temperature of 160°F (71°C) has been reached. These single-usetemperature indicator labels can be adhered to dishes, glassware, silverware, pots, pans, or other kitchenware. When the temperature reaches 160°F (71°C) or higher, the white dot on the label changes to black, clearly indicating that sanitization has been achieved TempDot features a transparent overlay to provide stability of the visual indicator dot. The label does not leave a sticky residue on kitchenware, so used labels are easily removed and can be affixed to a log book for record keeping.
high temperature thermal labels
Model 50109-50809, high temperature thermal labels are accurate, inexpensive, disposable heat indicators providing a permanent record of temperature changes. They come with one, three, five or eight temperature steps, available from 90°F (32°C) to 500°F (260°C).

When rated temperatures are reached at each step, an irreversible black color change occurs. These stick-on labels affix directly to the clean dry interior or exterior surface of products or equipment.

Applications include manufacturing, processing, storage, shipping, shelf temperature of heat sensitive products, for dishwashers, heat sanitizing, ovens, dryers, retort and curing operations.
