YSI Pro Plus Multi-Parameter Meter
The YSI Professional Plus handheld multi-parameter meter provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature. Also a very powerful lab instrument for BODs, pH and ORP.
EPA approved for drinking water and wastewater compliance reporting.
The Quatro cable attached to the Pro Plus allows you to utilize 4ports to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate creating an extremely powerful handheld multi-parameter instrument.
