Chemical Process Indicators (CPIs), ISO 11140-1 TYPE 1
True Indicating EO Chemical Process Indicator labels are manufactured with:
• Water-based Indicating Ink which contains no lead or other toxic heavy metals

The Indicators are designed to provide confirmation of exposure to an EO process through color transition from Purple to Green. The Indicators may be used to monitor EO exposures using 100% EO or gas mixtures. The color transition is designed to occur in compliance with ISO 11140-1 and display an irreversible change which is distinct allowing for processed from unprocessed items to be easily distinguished.
True Indicating offers three (3) standard configurations; see table below. In addition to standard configurations, True Indicating will manufacture custom Indicators and Labels to meet your needs.
