)
Tab. 3-9: Special Performance Specications for Gas Purity Measurements
All these performance data is veried during the manufacturing process for each unit by the
following tests:
Linearization and sensitivity test
Long term drift stability test
Climate chamber test
Cross interference test (if applicable)
