Ozone sensor

Someone know how can I could calibrate my ozone sensor? It is not necessary to be ozone sensor can be another gas sensor.

Put a known concentration of ozone on it and take a measurement. Repeat for a few different concentrations bracketing the range of interest.

Don't you think that telling us which sensor you have would help get better responses?

For a different gas sensor, use the method described in reply #1 with the appropriate gas.

What sensor? What is its range? Ozone gas sensor or dissolved ozone sensor for water? Or are you referring to some sort of "ozone pollution sensor"?

The known concentration would be the major problem. Ozone is very instable. You cant store it in a gas bottle. You have to generate it on-site, e.g. with an ozone generator. Than you get a few ppm or maybe a few percent, but how to determine this to calibrate afterwards the sensor? Do you use an MQ131?

My company works with high dollar ozone monitors from low range ambient safety monitors down in the 0.1-1.0 ppm range up to monitors measuring 20%wt ozone (about 130,000 ppm I believe). These monitors are very expensive. Some of our monitors can cost in excess of $10,000. We have a calibration source that we have to send to a lab to be calibrated annually.

Without any sort of calibration source as Jimbo_Jones said, I don't know how you would validate/calibrate an ozone sensor. This is assuming you are talking about ozone in air/oxygen. If you are talking about an ozone in water sensor 'DO3' this is another thing entirely. Also requires some calibration equipment although they are not quite as expensive.
