Iím happy youíre healing wonderfully, kerrlakelover!

Unfortunately, I donít have access to the information youíre seeking about the NOX sensor. However, I can look into the warranty and possible cost assistance with this. Iíll send you a private message of the information Iíll need to get looking into this for you.
