• Plain language screen prompts, soft keys that update for easy selection
  • AUTOREAD locks in the stable reading on your screen, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals
  • Up to five point pH calibration with automatic recognition for USA/NIST and DIN buffers and calibration editing to fix errors without a complete recalibration
  • No need to worry about DO probe compatibility – the meter accepts and automatically recognizes Orion polarographic and RDO optical/luminescence-based probes
  • Accurate DO results are easier with automatic temperature, manual salinity and automatic/ manual barometric pressure compensation
  • Calibrate DO by using water-saturated air, air-saturated water, a Winkler titration or zero point calibration
  • Non-volatile memory holds up to 2000 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
  • To mix samples without a stir plate or for faster BOD readings, meter can directly control the 096019 Orion Star stirrer or 086030MD Orion AUTO-STIR* DO probes (each sold separately)
  • Included electrode arm and newly-designed probe holder make it easier to maintain and place probes into samples
  • Works with almost every AC power source with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power
  • IP54-rated housing handles splashes and is wall-mountable if table space is a problem
  • Three year meter replacement warranty
