The Loggershop Guide to Temperature Indicators

What are temperature indicators or stickers used for?

Temperature indicators are used to record the temperature of a product during storage or shipping. They collect and store data on the time-temperature over a set period, enabling users to monitor the temperature conditions to ensure they meet regulations.

Indicators are available in the form of temperature stickers or temperature indicator strips. Depending on the reason for use, there’s freeze indicators in a choice of single-use or 3-year durations.

There are three types of temperature indicators that Loggershop stock:

These electronic temperature indicators are more robust than traditional temperature stickers and are a low-cost alternative to single-use loggers. The visual display makes it easy to monitor the temperature conditions, and (if using the interface cradle) critical data can be download for review. Choose from a 20-day or 45-day temperature indicator or a 3-year freeze indicator.
