NOAA National Centers for Environmental Information custodian coulometer for DIC measurement coulometer for DIC measurement measures dissolved inorganic carbon (DIC) A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The amount of CO2 in the resulting gas stream is determined by absorbing the CO2 in an absorbent. The pH of the solution is monitored by measuring the transmittance . thermosalinograph thermosalinograph automated sea surface temperature and salinity instrument, usually attached to the hull of a ship Thermosalinograph is an automated Sea Surface Temperature and Salinity measurement system making measurement on board a ship using a water intake.
