1. A device for determining sterilization conditions within a sterilization chamber, said device comprising an elongate tube to be placed within said sterilization chamber, said tube having a tube wall and a cavity therein and being open at one end and closed at the other end thereof, and at least two temperature sensors within the cavity of the elongate tube, wherein the at least two temperature sensors within the elongate tube each comprise a thermocouple and the at least two temperature sensors being spaced apart from each other along the length of the elongate tube by a predetermined distance and being spaced apart from an interior wall of the elongate tube;
wherein the wall of the elongate tube comprises at least first and second passages therethrough adjacent to each thermocouple, and each thermocouple comprises two wires, one wire extending through the first passage and the other wire extending through the second passage in the tube wall, wherein each wire has a thermocouple forming end for each thermocouple, the thermocouple forming ends of the two wires are connected, wherein each wire has a diameter of equal to or less than 0.4 mm wherein the device further comprises a processor adapted to determine, on the basis of the temperatures measured by the at least two temperature sensors within said tube in conjunction with a reference temperature determined at a location within the sterilization chamber but external to the elongate tube, whether predetermined sterilization conditions are met within said sterilization chamber, and wherein the device further comprises a pressure sensor external to the elongate tube. |
