In all supermarkets, convenience stores and petrol stations, refrigerated cabinets are available for storage and preservation of perishable foodstuffs. It is important that the cabinets work as efficiently as possible and do not consume too much energy, while keeping the goods at the correct temperature.
These units are equipped with a special cooling system, which requires pressure and temperature measurement to maintain the correct cooling temperature and the proper functioning of the cooling system.
On many cabinets, the temperature of the cooled goods is displayed.
