Total Dissolved Gas

Hydrolab's Total Dissolved Gas (TDG) sensor uses a pressure transducer mounted behind a rigid gas-permeable silicone membrane to measure amount of total gaseous compounds dissolved in a liquid.

Features
  • TDG is measured in units of pressure (mmHg) This pressure includes the partial pressure of all gas species dissolved in the water

Benefits
  • Real-time measurement indicates water supersaturated with atmospheric gases, which can cause gas bubble gill disease in aquatic organisms.

  • This pressure includes the partial pressure of all gas species dissolved in the water
