he HI9811-51 is an economical, wateproof, portable meter that measures pH, conductivity (EC), total dissolved solids (TDS) and temperature (°C) with a single probe. The meter operation is simplified with dedicated buttons for measurement modes to be be displayed on the LCD and knobs for single point calibration of pH and EC/TDS. The HI9811-51 is most suitable for agricultural, greenhouse and hydroponic applications.
