A device for testing the presence of air in a steam sterilizer for porous loads, comprising four porous masses (10) each formed from a stack of single rectangular sheets of spun-bonded polypropylene, each mass being contained and enclosed by perforated shrink wrapping film to produce a block of typically some 4 cm in height and typically some 15 cm square. Interposed between the masses (10) are envelopes (13) of a similar material, each containing a thermocouple and conductor leads. The assembled stack is contained by upper and lower end plates (15) and resilient side panels (16) which serve as clamps to compress the stack. When placed in a steam sterilizer under operating conditions, the device serves to test the accuracy and efficiency of the sterilizer by taking accurate temperature readings from the thermocouples placed at the different heights, and by comparing these readings to the temperature in the condensate drain passage of the sterilizer. |
