KnoOx’ 1000 Optical Oxygen Analyser System

OxySense is the first non-invasive oxygen measurement system for sealed enclosures such as ArchiPress, Escal Neo or other barrier bags. It is an optical system that can non-invasively measure oxygen concentration within packages that are transparent, semitransparent, and translucent; and as long as the packaging material can transmit blue and red light (at approximately 470nm and 610nm respectively), a measurement can be made.

This system allows the production of bar codes, which can be scanned by the portable KnoOx 1000 to uniquely identify the object and record the oxygen level with minimum disturbance to the items being stored.

The technology relies on The Oxy2Dot, which is a non-invasive, light-sensitive, oxygen sensor that is placed into the barrier bag prior to putting documents or objects in. Measurements are achieved simply with a fibre-optic reader pen from outside the package. All software required is included and is easily exported to Microsoft Excel for further analysis.
