A device for conditioning products intended to maintain the products within a determined temperature range, including a first box of parallelepiped shape; a second box of parallelepiped shape. The second box having overall dimensions less than the first box is intended to be positioned inside the first box in a removable manner. At least one thermal stabilisation element is intended to be positioned in a space formed between the first box and the second box. A temperature monitoring system includes a data monitoring unit and at least one temperature probe coupled to the monitoring unit. The monitoring unit is intended to be fixed onto the first box and the temperature probe is intended to be inserted into the second box. The second box includes a slot for positioning the temperature probe. The positioning slot maintains the temperature probe in position by compression.
