| Definition | The GTD-Pro is a total dissolved gas sensor, used to determine air-sea gas transfer rates, estimate net biological production, study near-surface fluxes, and correct measurements of other dissolved gases. It measures the sum of the partial pressures of all dissolved gases, i.e. gas tension, and comes with a 2GB internal data logger. The instrument can come in titanium housing, rated to 4000 m. Accuracy is 0.01 %, resolution 0.0001 % with a drift under 0.02 mbar a year. Range is 800-2000 mbar, and depth rating is 0-600 m. Equilibration time (t63) is 3 min. | |
