A method and related apparatus for monitoring steam conditions in a container, such as a beer keg, during disinfection, usually in a washer/racker. Temperature and pressure are taken repeatedly within the container during the disinfection process. Resulting temperature and pressure values are inputted to a data processor. The data processor establishes automatically whether the measured temperature and pressure values correspond to desired steam conditions within the container. These conditions are at, or within a predetermined tolerance from, a phase boundary between steam and water. An output is provided which includes a direct indication of whether the desired conditions are or have been met for measuring pairs of temperature and pressure values.

A method of monitoring steam conditions in a container during disinfection comprising the steps of: a) repeatedly taking measurements of the temperature and pressure within the container during disinfection; b) inputting measured temperature and pressure values to data processing means; c) establishing automatically in said processing means whether measured temperature and pressure values correspond to desired steam conditions within the container, such conditions being at or within a predetermined tolerance from a phase boundary between steam and water, by taking, for each simultaneous temperature and pressure measurement, the value of one parameter as a reference value, and establishing a target value for the other parameter representative of phase boundary conditions within the container, comparing the measured value of the other parameter against the target value, and determining if said measured value is within a predetermined tolerance from said target value; and d) providing an output including a direct indication of whether the desired conditions are or have been met for measured pairs of temperature and pressure values if said measured value is within said predetermined tolerance from said target value.
