  • Dissolved oxygen: (concentration – polarographic) 0.00 to 90.0mg/L ±0.2. (% saturation) 0.0 to 600.0 ±2%. (concentration – RDO) 0.00 to 50.00mg/L ±0.1mg/L up to 8mg/L; ±0.2mg/L from 8 to 20mg/L; 10% of reading from 20 to 50mg/L.
  • Dissolved oxygen: (% saturation – RDO) 0.0 to 500.0 ±2%. Manual barometric pressure correction: 450.0 to 850.0mm Hg. Manual salinity factor correction: 0 to 45ppt.
  • Temperature range: 0.0 to 50.0ºC (32 to 122ºF) ±0.1. Offset calibration: 1 point.
  • Log Function: Manual or automatic with AUTO-READ™. Log edit: delete last reading or all.
