Ethylene Oxide (EO) is a gas widely used for the sterilization of healthcare devices and instruments. The process involves exposing products to a gas mixture of EO and nitrogen within a vacuum-filled chamber. The EO gas acts as a surface sterilant and the vacuum environment aids the gas to reach most aspects of the device requiring sterilization. 6 Warner Road, Warner NH 03278 • P: (603) 456.2011 F: (603) 456.2012

EO gas sterilization is dependent upon four parameters: EO gas concentration, temperature, humidity, and exposure time. In accordance with ANSI/AAMI/ISO 11135, it is required by the FDA that temperature and relative humidity be monitored at different intervals during process validations on routine EO processed medical devices. Periodic chamber mapping and cycle validations are required to be performed to ensure even distribution of temperature and humidity levels throughout the chamber. MadgeTech data loggers can aid in: • Facilitating Parametric Release • Product Qualification Runs •...

How it M easures RHTemp1000IS A thin ≈ 1um plastic sheet with a porous platinum or gold metalization layer on each side. Water from the environment goes into the polymer and changes the dielectricity and thus the capacitance of the sensor. When used in an oscillator, the presence of water will change the outputfrequency. Output is proportional to relative humidity, rather than moisture content 6 Warner Road, Warner NH 03278 • P: (603) 456.2011 F: (603) 456.201
