9.1 YSI Conductivity Cells
YSI 3200 series conductivity cells have a built in temperature sensor for temperature
measurement and automatic temperature compensation. Dip, fill and flow-through conductivity
cells are available, each utilizing platinized platinum iridium electrodes. These cells have the
following specifications:

YSI also offers 3400 series cells which do not contain temperature sensors. Several dip and flow-
through conductivity cells are available, each utilizing platinized platinum iridium electrodes,
except the YSI 3418, which has platinized nickel electrodes. These cells require the 3232 cell
adapter for use with the YSI 3100 and will not provide temperature measurement,
temperature compensation or salinity. These cells have the following specifications:
