3.6 Measurement Specication
Special Performance Specications for Gas Purity Measurements (ULCO & ULCO2)

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)
