Fridge Temperature Monitoring


Identifying maintenance by interpreting data from a fridge temperature monitoring system

The optimum temperature for a fridge storing food or medical supplies is typically +2°C to +8°C, a higher temperature will result in rapid decay and a lower temperature will cause degradation, generating potential health risks if unknown. Therefore fridge temperature monitoring is critical to ensuring quality of contents are maintained.

Why not use thermometers or data loggers?

Initially, it may seem to be the better option because they are cheaper and accurate enough, right? But have you considered who is going to manually record the data, will the data be legible or forgotten, what happens out of normal working hours? There are a number of potential human error possibilities within these methods of monitoring and lets face it, they are just dated for this day and age where we rely on technology almost everywhere else.

Monitoring a fridge with wireless tech

Utilising wireless fridge temperature monitoring equipment with comprehensive software, users can not only save time from manual recording, but obtain critical information that can be easily analysed for various purposes at the click of a button.

The below example uses the Hanwell software to show some interesting temperature data of a fridge over the course of a normal working week.

You would expect a certain amount of temperature fluctuation over each day resulting its use during normal working hours, however this graph indicates extreme temperature fluctuations ranging from -5°C to +5°C, multiple times each day and outside of normal working hours.

By viewing the same data by day it shows a dramatic temperature drop below freezing point on a few occasions potentially compromising the contents of the fridge before staff return to work. Not only could this cause potential health risks for those using the fridge contents, but it is also potentially using more energy than required.

By overlaying another office fridge sensor within the same building (example below in yellow), you can quickly eliminate the possibility of power failures or fluctuations influenced by extreme weather conditions as this additional fridge would show the same or similar results.

Ultimately the graph highlights that the office fridge isn’t performing correctly and the fridge contents are being compromised. The user is now able to repair or replace the fridge before it breaks down completely. Without the use of wireless monitoring these temperature irregularities could have gone unnoticed.
