The HI9813-5 is an economical, water resistant, portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature with a single probe. The meter operation is simplified with dedicated buttons for measurement modes to be displayed on the LCD and knobs for single point calibration of pH and EC/TDS. The temperature coefficient is fixed at 2%/°C.

This meter comes with:
