Hydrolab

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

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
