The YSI Professional Plus handheld multiparameter water quality meter provides reliable field measurements for dissolved oxygen, conductivity, resistivity, specific conductance, salinity, total dissolved solids (TDS), barometric pressure, pH, and ORP. The Professional Plus is rugged, light weight, and provides all water quality field measurements on one screen! No need to cycle through various screens to take down measurements.

Parameter Range Accuracy Resolution
Dissolved Oxygen (%) (temp comp range -5 to 45°C) 0 to 500% 0 to 200% (± 2% of reading or 2% air saturation, whichever is greater) 200% – 500% (± 6% of reading) 1% or 0.1% air saturation (user selectable)
Dissolved Oxygen (mg/L) (temp comp range -5 to 45°C) 0 to 50 mg/L 0 to 20 mg/L (± 2% of reading or 0.2 mg/L, whichever is greater) 20 – 50 mg/L (± 6% of reading) 0.1 or 0.01 mg/L (user selectable); 0.1% air saturation
