The hi9811-5 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 hi9811-5 is most suitable for agricultural, greenhouse and hydroponic applications.
