Hi Eric We have some Anoxibug units that have been in use for some years (at least 8-10 years - we did change the oxygen sensor in one unit about 5 years ago). I routinely check them against our other oxygen meters, and they are still operating within range. In between use they are stored in low oxygen. I’m overseas until Friday so I can’t get them to you by the 28th, but I would be interested in your results. Best wishes Alex Alex Roach Modified Atmospheres
