O2-Sensors

your questions - our answers!

BlueSens offers two different measurement principles for oxygen. What is the difference between them?

With an appropriate calibration electrochemical oxygen sensors can be applied for the entire measurement range from 0 to 100vol%. Sensors with ZrO2 (zirconium dioxide) are characterized by a very noiseless signal, but are restricted to a measurement range.

Attention! The BCP-O2 with ZrO2 must not be used with flammable or explosive gas mixtures.

Can the O2 sensor be used under anaerobic conditions?

BCP-O2 always needs a minimum concentration of oxygen for that the sensor element will not be damaged. The minimum usually is equal to the smallest value within the measurement range (meaning 0.1 vol. % with a measurement range up to 25 vol.% O2 and 1 vol.% O2 with a measurement range up to 50 vol. % O2). This minimum amount of oxygen must be ensured during the whole measurement.

Do not use the BCP-O2 in processes without oxygen! For measurements without oxygen we recommend to use the BCP-O2e

What do I have to consider for storing the sensors?

Both sensors must be stored at 0 to 60°C. In addition to that the following sensor specific specifications have to be taken into account:

  • BCP-O2: During storage relative humidity is not allowed to be more than 75% (non condensing)
  • BCP-O2ec: During storage relative humidity must be between 5 und 100 % (non- condensing)
