NEPTUNE SYSTEMS APEX PROBE CONDUCTIVITY/SALINITY CALIBRATION SOLUTION 53000 µS Magnesium The control valve let you53000 S Conductivity Calibration Solution Use this calibration solution to calibrate your Conductivity Probe and PM2 for saltwater salinity monitoring applications. Conductivity probes can be used for many different functions from letting you know the salinity of a tank to the quality of RODI water. We suggest calibrating conductivity probes once every 3 6 months to keep readings reliable. 447 S Conductivity Solution Used for calibrating conductivity
