Food retail: carbon dioxide and humidity monitoring

In brick-and-mortar food stores, it is necessary to monitor carbon dioxide (CO2) and maintain it at a certain level to protect the health and safety of customers, staff and contractors. 

Moreover, CO2 is commonly regarded as the ideal natural refrigerant. It is a non-toxic, non-flammable, odorless, colorless gas, however, its high concentrations can cause unconsciousness and even death, so accurate, reliable monitoring is necessary for safety reasons and for the rapid detection of potential leaks. Synthetic refrigerants can be powerful greenhouse gases and have a global warming potential (GWP) that is thousands of times higher than that of carbon dioxide. 


Recently, more and more countries recognize the need to turn to the use of environmentally friendly refrigerators in supermarkets and make respective regulations for retail. As a result, there is a growing number of transcritical CO2 stores that use carbon dioxide to replace the synthetic refrigerants in all supermarket refrigeration, in store and back of house. 


The use of CO2 in the refrigeration systems allows to lower greenhouse emissions whilst lowering operational costs as well. This is possible with Vaisala's carbon dioxide probes based on the unique CARBOCAP® technology which help to identify and reduce possible refrigerant leakage. 

Solutions for environmental monitoring in retail

Monitoring of temperature, carbon dioxide (CO2) and relative humidity for maintaining the highest quality product assortment and personnel well-being in brick-and-mortar grocery stores, supermarkets and retail chains.

CO2 monitoring in supermarkets

In food retail, excessive accumulation of carbon dioxide can be detrimental to the well-being of customers, personnel and contractors or reduce their productivity during the working day. It is therefore necessary to monitor and maintain CO2 at a certain level.

Also, reliable monitoring of CO2 can help to detect possible refrigerator leakage. CO2 is a natural refrigerant that has drastically lower global warming potential (GWP) than synthetic refrigerant gases. 

Learn in the customer case how supermarkets are benefiting from the advanced carbon dioxide monitoring.

Humidity monitoring in brick-and-mortar retail

To protect fruit and vegetables against loss of moisture, decay and aging, and ensure the best product quality to your customers, it is important to monitor relative humidity in the retail food stores.
