Oxygen Probe CarboProbe DS for laboratories, universities (%O2)


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 extension tube over the first 50 mm of the sensor.
  • 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

Works great with our ControX display and control module
