YSI Pro Series 20 DO Sensors

Available Sensor Options:

  • DO - Polarographic
    • Longer life saves time, money and reduces over all costs.
    • Requires a warm up/stabilization period
    • Measures Oxygen based on current generated when oxygen is reduces at the cathode under applied voltage
    • Good for long term monitoring setups
  • DO - Galvanic 
    • Quick start without a need to warm up
    • Self polarizing
    • Measures oxygen with the same reaction as polarographic, but generates its own voltage via electrode chemistry.
    • Great for periodic sampling and quick field checks
