Segment Reporting Disclosure [Text Block] | Note 1 5 . Segment Data As of March 31, 2016, our four operating segments were Biological Indicators, Instruments, Continuous Monitoring and Cold Chain. Effective April 1, 2016 we renamed our Continuous Monitoring and Cold Chain operating segments to Cold Chain Monitoring and Cold Chain Packaging, respectively.
