Hello Everyone,

I am curious to know if anyone has any recommendations for oxygen sensing equipment to be used in anoxic treatments that is cordless and could be left inside the chamber.  It would be viewed through a window to verify oxygen levels at any time during the treatment.  The oxygen sensor that we currently use has a cord, so once levels reach the appropriate point, the sensor must be pulled out before the chamber is fully sealed.  At that point, it is up to the "purple/pink pills" to give an indication of oxygen levels.  Those pills seem to be a little unreliable, and we are looking for equipment that could be a little more clear about what exactly the level is inside the chamber.    

Does anyone have experience with any of these sensors?

If anyone has any thoughts about the equipment above, or other devices, they would be appreciated.

Thanks,
