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.
Special features

Low drift
Long lifetime
Fast response
Digital output of all major oxygen units
Technical Data Sheet
The OxyGuard TGP probe measures Total dissolved Gas Pressure and is designed specifically for use with OxyGuard Commander or Pacific systems. It can be added to existing systems. It contains sensors for dissolved gas pressure and temperature. The gases dissolved in water consist of oxygen and “other gases”. “Other gases” are mainly nitrogen. It is important to measure if the water is supersaturated in order to prevent the fish from getting gas bubble disease.
The Commander or Pacific system to which the probe is connected uses a dissolved oxygen measurement made by a DO probe placed near the TGP probe for calculations and presents the degrees of saturation for the total gas, dissolved oxygen and for other gasses.
