Description
OxyGuards new optical oxygen probe is developed in cooperation with world leading experts. Based on luminescence quenching of a sensor dye immobilized on a support foil it can be used for gas measurements as well as for dissolved oxygen (DO).
The presence of molecular oxygen quenches the luminescence, changing its intensity and lifetime fully reversibly. The measurement principle is very robust. It shows virtually no interference to other gases and has very low drift. Bleaching is not an issue because low energy red light excites the sensor spot and emission is NIR.
