ABSTRACT:
An improved steam sterilization process monitor is disclosed comprising a backing strip, a wicking means in intimate contact with an organic compound mounted on the backing strip and a water vapor rate controlling cover strip. In the preferred embodiment the backing strip comprises aluminum foil having a polypropylene interlayer adhesively bonded thereto. The sole means for bonding the cover strip to the backing strip is by heat sealing. The cover layer is heat sealed to the backing strip over the entire land area of the backing strip surrounding the wicking means, but is not heat sealed to the wicking means. The organic compound has a normal melting point in the absence of water vapor of about 5.degree. to about 50.degree. F. above a predetermined control temperature.
