Oxygen sensor up to 50%

Question

Are there any oxygen sensors that measure up to 50%?.

As I understand, there are sensors that measure only in range 0-30%.

Is it possible to increase the threshold of sensitivity of the sensor?

Answer 1

You can try SO002 or DS-TR250.

Is it possible to increase the threshold of sensitivity of the sensor?

I don't think its possible. Perhaps you can tweak the reading sensitivity, but since the sensor are mostly analog, it's not possible. And maybe that also the reason the 2 sensors I've mentioned above have several series based on their measuring threshold.

Answer 2

The Bosh LSU 4.X sensor(s) are what I think you are looking for. Here are some related links:
