Tokyo – October 12, 2026 -- NTT, Inc. has cut the maximum relative error of sensor-based CO2 absorption monitoring in microalgae cultures from approximately 3,300% to approximately 8%, measured against the conventional titration method.
The technology calculates dissolved inorganic carbon (DIC) concentrations from CO2 and other sensor readings. It does not require sampling the culture fluid for each measurement. The results were published in the journal Algal Research on August 12, 2026.
