The YSI Professional Plus handheld multiparameter 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.
 
The Quatro cable attached to the Pro Plus allows you to utilise 4-ports to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate creating an extremely powerful handheld multiparameter instrument.
 
When purchasing the Pro Plus you will receive the instrument, manual, batteries, communications saddle, USB cable, and Data Manager software. Cables and probes are ordered separately.
