This new model provides accuracy and reliability in measuring conductivity, salinity and temperature. The instrument uses forced-current measurement technology, and includes direct-reading digital display, adjustable temperature coefficient, and automatic temperature compensation. Range from 0 µS to 499.9 mS. The new 30965 series of conductivity cells were designed for the new 3200 and 3100 meters. Old YSI 3400 series probes can also be used with the new 3232 cell adapter. Order cells separately.
