Abstract
The operation of a steam sterilizer is monitored by a test unit and a controller which together comprise a system which can be operated in two principal method schemes: (1) the testing for completeness of air removal from a sterilizer chamber, and (2) the testing for effective sterilization conditions. These methods each have two principal modes of operation: (a) the performance of a Bowie and Dick type test, as is usually done on a once-a-day basis; and (b) monitoring the sterilizer during load conditions. In a preferred embodiment a test unit including temperature and pressure sensors, a moisture sensor and a heat sink are positioned within the chamber of a steam sterilizer and transmit by radio the conditions therein to an external controller. The test unit can employ a replaceable cartridge to assure effective operation even after a large number of cycles of operation.
