Dissolved Oxygen Meter From Cole-Parmer

Cole-Parmer supplies a range of dissolved oxygen meter (DO) instruments , controllers and probes which are suited for many different applications. The DO range provide accurate measurement of the concentration of dissolved oxygen in a unit volume of water.

One instrument in the extensive DO meter range offered by Cole-Parmer is the YSI 5100 OUR/SOUR DO meter. This is a benchtop DO meter which offers onboard storage of up to 100 data sets, a real time clock and autocalibration functions. It’s easy to use and the keypad controls reduce the risk of operator errors by providing an audible confirmation for input. Oxygen and specific oxygen uptake rate (OUR/SOUR) can be measured using the 5100’s integrated software.

Features of the 5100 OUR/SOUR benchtop dissolved oxygen meter include:

  • Large LCD display is easy to read, even from a distance of ten feet
  • User friendly menu driven interface with audible confirmations
  • One button autocalibration
  • Bidirectional RS-232 interface
  • Dissolved oxygen range of 0.0 to 60.0 mg/L
  • Accuracy of ±0.1% + 1 LSD
  • Resolution of 0.01 mg/L
  • Saturation Range of 0 – 600% with resolution of .1% and accuracy of ±0.1% + 1 LSD
  • Barometric pressure range 0 – 1500 mbar with 1 mbar resolution and ±1% + 1 LSD accuracy
  • Automatic barometric pressure compensation 450 to 825 mm Hg (600 to 1100 mbar)
  • Temperature range of -5.0 to 50.0°C with resolution of 0.01°C and ±0.1°C accuracy
  • Automatic temperature compensation
  • 0 – 40 ppt salinity compensation


The 5100 dissolved oxygen meter features an integrated membrane replacement indicator (complies with US EPA regulations)
