Conductivity and temperature sensor

INFINITY-CT is an accurate conductivity and temperature meter making use of 7-electrode sensor. This 7-electrode generates an electric current only inside of the conductivity cell, minimizing external influences and improving data quality. Thus, precise salinity measurements are possible under bio-foul forming conditions. The compact design is suitable to be deployed/integrated with various sites/platforms. The instrument has two depth rating versions, shallow water (200 m, A7CT2-USB) and deep water (2,000 m, A7CT-USB and 1,000 m, A7CT-CAR/CAD).
