Fridge-tag 2 L Accessories

We offer you the following products and services for your refrigerator temperature logger solution



Software for Data Management

Berlinger offers a fully integrated temperature monitoring solution based on Berlinger’s Q-tag and Fridge-tag devices in combination with the Berlinger SmartView platform with its different business logic modules, its Application-Programming-Interface (API), to integrate with other systems.

Product benefits

  • Reduce admin time, reduce manual handling and associated risks.
  • Reduce the risk for dispensing drugs potentially affected by a temperature deviation.

Product benefits

  • Between your Software environment and SmartView
  • Easy and at highest quality standards
Simple and secure

Software for Data Verification

Berlinger offers solutions that increase security or simplify processes. 

Product benefits

  • Secure data
  • Authenticity of generated data
  • Easy to use

External Sensors

The external sensor brings the advantage that only the flat cable needs to be put in the freezer / cold room and the Fridge-tag device can be fixed outside. This reduces temperature fluctuations as the door of the freezer / cold room does not need to be opened to read out the Fridge-tag. 

Product benefits

  • A shorter battery life can be avoided with the use of an external sensor.
  • Available in 1 meter or 1.5 meter flat cable, whichever best suits your needs.
  • Attach the Fridge-tag to the outside of the fridge/cold room and route the flat cable into the fridge/cold room.

Product benefits

  • A shorter battery life can be avoided with the use of an external sensor.
  • Available in 1.5 meters (flat cable), 1.7 meters or 2.3 meters (round cable), whichever best suits your needs.
  • Attach the Fridge-tag to the outside of the freezer/cold room and route the flat cable into the fridge/cold room and secure it with the vacuum cup.


Increase and secure your quality with regular, high-precision calibration of your temperature monitoring devices. We are proud that we successfully accomplished the accreditation process and are running our own calibration laboratory according to ISO 17025

Product benefits

  • SAS calibration laboratory according to ISO 17025
  • Calibration or recalibration from -40°C to +80°C


The Fridge tag 2, Fridge-tag 2 E, Fridge-tag 2 L and Fridge-tag Ultra Low have been validated by the makers of the Varo app, to be compatible with the free Varo mobile application, which reads out data from the Fridge-tag loggers and sends it via email to user-defined recipients in a format that can be easily aggregated using a separate free application called Pogo LT.

Product benefits

  • Our Fridge-tags are the first temperature monitoring devices which are compatible with the free Varo mobile application
  • It's a simple, effective, free to have and free to use private tool to make vital information more accessible and useful.
  • Read out your Fridge-tag easily

Fridge-tag 2 L

Audible alarm
A powerful and competitive novelty is the audible alarm signal. The Fridge-tag 2 L 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 clearly 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.


How to use

Learn how to turn on the Fridge-tag 2 L and is set up for initial use. Step-by-step instructions explain how to change the date, time and the temperature unit.

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.
