Ohaus STDO11 Dissolved Oxygen Probe

The OHAUS Starter Series are designed to produce exact results time and time again.  They fit perfectly in holders on OHAUS bench meters as well as clips on all OHAUS portable meters. 

There are three types of commonly used oxygen sensors: polarographic, galvanic and optical (luminescence) sensors.  STDO11 is a galvanic DO probe and the simplest among the three probes. 


  • Connection: BNC
  • Cable Length: 1m
  • Shaft Length: 120 mm
  • Shaft Diameter: 12 mm
  • Shaft Material: Plastic
  • Temperature Range: 0-50 ˚C
  • Measurement Range: 0-200%
  • Storage Solution: 10% NaCl


Carefully remove the protective bottle from the tip of the electrode by unscrewing the lid and removing the bottle.  Remove the shorting plug from the connector and store in a safe place.  Be careful because the protective bottle lid is tightly fit on the electrode.  STDO11 should be stored in a moist environment to keep the membrane from drying out, but do not store directly in water.

DO probes should be calibrated before being placed in the sample.  Before calibrating a probe, do not forget to remove water droplets from the membrane by gently shaking the sensor.
