Hello,

 

Sorry for the stupid question.

 

I bought the Gravity: Electrochemical Oxygen / O2 Sensor (0-100%Vol, I2C) and I am trying to calibrate it.

 

I understand that for the 20.9% calibration you can use the normal environment.

 

I don't know where to place the probe in a pure oxygen environment for the 99.9% calibration.

 

Can you please advise me what I can use?

 

Thank you in advanced.

You can purchase or rent a medical oxygen cylinder (often ~99.5% to 99.9% purity).

You must regulate the flow using a low-flow regulator (e.g., 0.5–1 L/min) to avoid damaging the sensor or causing turbulence.

Place the sensor in a small chamber or fit tubing over the sensor inlet and gently flow the oxygen around the sensor.
