Point Four Systems Optical DO/TGP Probe

The Lumi4 DO/TGP Optical Probe allows users to simultaneously measure multiple parameters - Dissolved Oxygen (DO), Total Dissolved Gas Pressure (TGP) and temperature with a single probe.

Increasing water temperatures, injection of air in water, algal blooms, or pumping can result in gas supersaturation. This may lead to bubble trauma or sub-lethal toxicological problems for aquatic life.

The TGP probe provides an accurate measurement of total dissolved gas pressure. With the addition of an oxygen probe, the user can determine the percentage of TGP attributed to nitrogen & other gases.
