Oxygen gas sensor

The measurement of the oxygen concentration within the packaging is done by a contactless non-intrusive laser gas sensor.

The utilized sensing method is the Tunable Diode Laser Absorption Spectroscopy (TDLAS).

TDLAS is a well-known optical method to measure gas absorption with great sensitivity and accuracy.

The sensors can operate on packaging units (containers, bags, cups etc.) whose optical properties varies from the high transparency, which enables viewing of packed products, to almost opaque walls, which screen the content from the day light
