Fridge-tag 2 Accessories

We offer you the following products and services for device.


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

Detailed evaluation of temperature threshold violation
The Fridge-tag 2 shows irrevocably the exact point in time and the date of the first limit violations. Additional information such as how long limits were exceeded and the highest and lowest temperatures help in making binding decisions. The details can be easily read on the device and in the easy-to-read PDF report.

Individual alarm programming
Two alarm limits (one upper and one lower alarm limit) can be programmed individually at a temperature range of –20°C up to +50 °C. The alarm limits can be ordered either as default factory settings or set personally on-site.

Exact measurement of temperature and time
The Fridge-tag 2 is a high-precision, electronic temperature monitor. Calibration traceable to ILAC recognised international standard (e.g. SAS, NIST) upon request. The sensor has a measurement precision of +/– 0.5°C. Temperature measurement occurs every minute throughout the entire monitoring time. This guarantees faultless and extremely accurate measurement results. Even if an alarm limit has been exceeded and the Fridge-tag 2 alarm is displayed, it accumulates each additional temperature threshold violation.
