pO2 & pCO2 Micro Electrodes

The new pO2 probe can be used to measure pO2 of tissues, whole cells, cell fractions, and various types of respiration studies. It can also be used to measure dissolved oxygen in biological and environmental samples. The pCO2 probe can be used to measure pCO2 in blood, fermentation studies, and various tissues. The pO2 probe has a 2mm tip and a 6mm body diameter. The pC02 probe has a 9mm body diameter.

Dissolved Oxygen Probe

Measure dissolved oxygen using your pH meter

  • Use with any pH Meter. Probe can be plugged directly into any standard pH meter for dissolved oxygen measurements.
  • Covers Full DO Range. Electrode can measure dissolved oxygen from 0 to 20 ppm or 0 to 150% saturation.
  • Eliminates Winkler Method. Probe measures dissolved oxygen directly without involved wet chemistry of titrations needed with the Winkler method.
  • BOD Measurements. BOD probe fits directly into BOD bottle for 5 day or continuous BOD measurements.
  • Portable. On-the-spot field measurements of dissolved oxygen can be made without a trip back to the laboratory.
  • Rapid Response. Typical response time at room temperature is 12 seconds.
  • Use for both BOD measurements in the LAB and for Field use.

Oxygen Range: 0 to 20 ppm dissolved oxygen
Accuracy: +/- 0.2 ppm at calibration temperature
Temperature Range: 0 to 50 degrees C
RESPONSE TIME: Response time at 25 C is 12 seconds for 90% of reading.
Connector: Available in either U.S. standard or BNC connector (please specify when ordering).
Power: 9 volt disposable battery.
Sample Size: Minimum sample size is about 2 ml.
