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)
