Signatrol has launched a low-cost, immersible, miniature data logger for use by bakery and ready meal manufacturers to record product temperatures throughout the product manufacture cycle.

The SL63T temperature data logger is made from food-grade materials and is fully encapsulated, so it can be immersed into liquid, such as pie fillings, without needing protective enclosures. This immersion-ready design is also especially useful in food R&D, frozen cooking validation, HACCP workflows, and during production washdowns where protective housings can be difficult to clean.

One SL63T data logger can be used to measure the whole cook-chill-frozen process from -40°C to +125°C (-40°F to +257°F) with an accuracy of ±0.2°C (±0.4°F).

Compared to similar data loggers on the market, the SL63T has improved accuracy and a larger non-volatile memory, so the data can be downloaded should the battery be depleted.

The Signatrol SL63T data logger communicates with TempIT5 software via the USB-powered NFC reader for configuration and data retrieval.  The TempIT5 software also has a remaining battery life feature, and the stored data can still be downloaded even if the data logger battery is dead.

Starter kits are available with either two or five SL63T temperature data loggers, USB interface cable and the TempIT5-PRO software.
