447 µS Conductivity Calibration Solution - Use this calibration solution to calibrate your Conductivity Probe and PM2 module for RO/DI water quality and other freshwater 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 µS Conductivity Solution - Used for calibrating conductivity probe for freshwater applications.

53.0 µS Conductivity Solution - Used for calibrating conductivity probe for saltwater applications.
