Demand for Temperature Data Loggers to Monitor COVID-19 Vaccines

CLEVELAND - Jan. 14, 2021 - PRLog -- With the approval and distribution of the Pfizer and Moderna COVID-19 vaccines, many clinics and pharmacies have begun their search for a solution to monitor vaccine temperature that meets the requirements of keeping the COVID-19 vaccines safe. According to the Center for Disease Control (CDC), the Moderna COVID-19 vaccine should be stored long-term in a freezer at a temperature between -25°C and -15°C (-13°F and 5°F) or in a refrigerator at a temperature between 2°C and 8°C (36°F and 46°F) for up to 30 days before the vaccine vial seal is punctured. The Pfizer-BioNTech COVID-19 vaccine has slightly stricter requirements, needing an ultra-low freezer with temperatures between -80°C and -60°C (-112°F and -76°F) for long-term storage. The vaccine can be stored in a refrigerator prior to mixing for only 5 days (or 120 hours) at a temperature between 2°C and 8°C (36°F and 46°F).

With these stringent requirements, the CDC requires the use of a Temperature Monitoring
Device (TMD) such as an electronic Digital Data Logger (DDL) to ensure that the temperature during the storage and handling of the COVID-19 vaccines is maintained properly and safely.

Key Features of a Temperature Data Logger

A key feature when using an electronic data logger is the ability to accurately determine the temperature of the vaccine. The devices normally use some type of probe that is placed within the refrigerator or freezer compartment. To accurately reflect the actual temperature of the vaccine, the CDC recommends the use of a thermal buffer – glycol bottle, glass beads, or Teflon block – on the probe to dampen temperature fluctuations due to door openings, etc.

Vaccine Temperature Monitoring Solutions

For small scale vaccine storage, there are two key kits:

T&D TR-75wb Kit for the Pfizer Vaccine storage (down to -199 Deg C)

T&D TR-71wb Kit for the Moderna Vaccine storage (down to -40 Deg C)

Each kit can monitor the temperature of two storage environments – with two temperature probes in each kit. Each kit comes ready to deploy and meets the CDC requirements for monitoring the storage temperature of the COVID-19 vaccines, including a NIST Traceable Calibration Certificate.

On top of solutions to monitor Covid-19 vaccines, we can also help you with any temperature monitoring solution from the smallest refrigerator to large scale freezer farms or even transportation monitoring. Give us a call at 800-956-4437 or visit us at
