Freezer Temperature Monitoring
Freezer Monitoring Systems for all Applications
Freezer data loggers for freezer temperature monitoring
In many industries, the only way to preserve or maintain product quality is through ultra-low temperatures. Storage and refrigeration of this kind require the most robust and reactive freezer temperature monitoring system because a deviation by even 1 degree can cause disastrous repercussions.
The core reasons for freezer temperature monitoring include:
Product preservation - preventing spoilage of various temperature-sensitive products, particularly biological materials, specimens and reagents. Ultra-low temperature storage is also common in vaccine monitoring.
Regulatory compliance - meeting the standards laid out by bodies including the FDA, WHO, HACCP and many more calls for proper documentation, audits and inspections of freezer monitoring systems and proper freezer temperature monitoring processes.
Financial risks - protecting organisations and businesses from costly inventory losses caused by temperature excursions.
Sustainability - achieving sector-specific energy and environmental ambitions through proper freezer performance where data from monitoring systems is assessed.

Expectations of Freezer Monitoring Systems
As mentioned, freezer temperature monitoring is predominantly required in industries where the stored goods are of biological origin, this includes vaccines (specifically mRNA vaccines which require storage at -70°C) and biological samples (generated regularly in research labs for the continuous development of drugs, pharmaceuticals and disease intelligence).
Proper freezer monitoring systems protect these sensitive goods against temperature deviations. The two core causes of fluctuations in frozen temperatures include:
Temperature Uniformity
With a freezer unit or instrument, temperature uniformity can have a significant impact on the stability of stored goods. Why? With ultra-low-temperature storage it is easy for larger units to have hot and cold spots, typically caused by ice build-up and other factors, which means that depending on the location of the goods, the temperature could deviate slightly.
Temperature Recovery Time
With recovery time, in a fast-paced lab, the door can be opened and closed multiple times as samples are brought out for thawing and use. Each time this occurs, the internal temperature must be restored back to its previous conditions as quickly as possible. this can cause momentary deviations which can have a significant impact. Human error can also play a role in integrity because if the door to a freezer isn't properly closed, all samples become at risk.
Setting up freezer temperature monitoring
Temperature conditions can have several impacts on your product or process. Adverse conditions can cause product degradation or safety issues. Freezer temperature monitoring is perhaps even more critical given that many frozen products are even more susceptible to a deviation in temperature which will often result in being wasted in the event of a temperature failure.
Should hardware fail and temperature deviations occur, then alert notifications are crucial. By providing key personnel with a warning, emergency action plans can be implemented to intervene and protect samples and invaluable products.
Freezer data loggers & freezer monitoring systems
We work with various market-leading brands to provide a strong portfolio of freezer monitoring systems and freezer data loggers. With various loggers offering an expanded temperature range, reaching as low as -200°C, we can help you identify the perfect freezer temperature probe. We also provide trials of many systems, calibration for ongoing performance validation and rental packages to cover any downtime.
