For use with YSI conductive instruments as well as with instruments of other manufacturers.

These precision cells contain platinized platinum-iridium electrodes. 23201-125 has nickel-rod electrodes. Conductivity cells require cell adapter 66121-968 (sold separately) when used with YSI Models 3100 and 3200 conductivity meters. Choose cells made from Pyrex® 7740 or ABS plastic.

Note: Cell constant values are calibrated within 1% of cell constant.
