The meter itself is fully waterproof and will float in water if accidentally dropped. Calibration of conductivity and pH is as easy as it is automatic. The TDS conversion factor is user-selectable. Automatic compensation for temperature. To use this meter you will need pH, conductivity and TDS buffer solutions for calibration, and electrode storage solution.
