Calibration Methods
• Water-Saturated Air (Air) – Thesimplestandmostaccuratemethod,thismethodusesthe
calibration sleeve included with the DO probe. Due to the inherent differences between water
saturatedairandair-saturatedwater,102.3%saturationwillbedisplayedwhenthecalibration
readingisstableusingapolarographicDOprobe.Forbestaccuracy,thecalibrationtemperature

sleevewithdistilledwaterandinserttheprobeintothesleevewithouttouchingthe
water-saturated material.
• Air-Saturated Water (Water) – Usewaterthatis100%saturatedwithair.Bubbleairintoawater
sampleforanextendedperiodoftime,preferablyovernight.
• Winkler Titration (Manual) – This method uses a water sample with a known concentration
ofdissolvedoxygenandcanbeusedtocalibratetheDOprobetothevalueachievedbyaWinkler
titration.AmanualcalibrationinvolvesperformingaWinklertitrationandusingthatsampleasa

meterinputtotheWinklertitration.Duetothepossibilityoftitrationerrors,thismethodisinherently
less accurate.
• Set Zero – Azeropointcalibrationrequiresoxygen-freesolution.Thismethodneedstoberepeated
eachtimetheprobeisreplacedormodied(capchangewithRDOprobes;membranechangeor
