  • No need to worry about DO probe compatibility – the meter accepts and automatically recognizes Orion polarographic and RDO optical/luminescence-based probes.
  • 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.
  • Waterproof with a IP67-rated housing.
  • Large, backlit graphic LCD display.
  • Display shows dissolved oxygen in % saturation or concentration with temperature and electrode status, time, date, sample ID, user ID and calibration points.
  • Advanced features such as stability and averaging options provide additional options allowing for laboratory accuracy everywhere you need it.
  • Accurate results are easy with ATC, manual salinity and automatic/manual barometric pressure compensation.
  • Calibrate using water-saturated air, air-saturated water, a Winkler titration or zero-point calibration.
  • AUTO-READ™ locks in the stable reading on your screen, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals.
  • Non-volatile memory holds up to 5000 data points with time and date stamp.
  • Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software.
