ABSTRACT:
A self-contained electronic test pack utilizes parametric measurments to determine the efficacy of a sterilization cycle. The electronic test pack is placed within a sterilization chamber and monitors and records environmental parameters at two predetermined locations during the sterilization cycle. More specifically, the test pack provides a challenging medium to challenge sterilant penetration to a first location and measures a first environmental condition at that location, and measures a second environmental condition within the sterilization chamber. The test pack records data associated with the first and second environmental conditions as well as time data from a timer within the test pack. The test pack may further process the data to determine whether adequate sterilant penetration has been achieved, or may transfer data to external devices to process the data.
