concentration probe concentration probe - CarboProbe DS


  • Measured value:

    concentration, oxygen

  • Technology:


  • Field:


  • Other characteristics:



The CarboProbe DS is a laboratory oxygen probe, suitable for measurement of oxygen concentration over the range from pure oxygen down to 10-24 atmospheres at temperatures from 700°C to 1700°C. It consists of a ZRO2 oxygen sensor with an internal thermocouple. All wiring and electrodes are platinum, for the best possible corrosion resistance.
•Supplied with a vacuum sealed, stainless steel M16 extension tube
•This extension tube can easily be fitted into an O-ring seal Accurate enough for research laboratory use, but low in cost
•Read the probes measurement with a hand-held digital meter, for a quick and simple reading.
•Student laboratory experiments – demonstration of the Nernst equation Combustion and pyrolysis research
•Measurement of fuel/air ratios in combustion
•Oxygen fugacity measurements in geological specimens
