A display cabinet and backroom store are different equipment; matching display readings do not prove that the product has had the same conditions. Sensor position and product requirements matter.
Keep loggers at a fixed, identified position in each unit. Do not block the cabinet loading line or air outlets; follow the case maker's layout instructions. Measure product using the method in its label or quality procedure.
Record lot, loading, time and door openings. This lets you compare changes in the cabinet and store and investigate where conditions diverge from product requirements.
