YOUR APPLICATION ADVANTAGES
Fridge-tag Ultra Low
Audible alarm
A powerful and competitive novelty is the audible alarm signal. The Fridge-tag Ultra Low automatically triggers an alarm, if a critical temperature deviation outside the predefined temperature range is measured. This enables you and your staff to react just in time.
Selectable recording duration up to 112 days
Enjoy extended temperature recording up to 112 days (selectable recording duration of 28, 56, 84 or 112 days). The built-in USB connection generates a secure PDF/A report with all relevant temperature data presented in a clear and easily understandable manner.
Document management and archiving
The ASCII and PDF/A files generated in the device can be sent back to the sender via email. They can organise the quality check, analysis and storage of the files. The data can be converted and read directly into the existing reports, ERP or data management systems. The information is therefore directly and automatically assigned to the relevant products.
The Berlinger Team is here to provide you with more information and answer any questions you may have. We will be pleased to advise you.
