Pro Plus

This is a handheld unit. Probes are connected to the unit for measuring the parameters of interest: oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature. The sensors and additional cables and are purchased separately.
