Message: <blockquote data-quote="Diver1975" data-source="post: 1356482" data-attributes="member: 370833">I tried my brand new Abbott freestyle libre sensor in Nemo33 which was until some year(s) ago the deepest pool in the world, and the sensor still worked fine afterwards. I went to 33m for a few minutes, and a total duration of 50 minutes. Water temperature was a comfortable 30°C. To be sure I taped a large patch of Suprasorb film dressing on the sensor that appeared to keep the sensor dry even at those pressures. I compared the scanning test with an actual blood sample test and the readings agreed quite well.These preliminary results are very promising. More tests in colder water (in Belgium as low as 5° Celsius) and salt water are needed, and with older sensors, but at some time I hope to take the scanner itself in an underwater house for underwater blood sugar testing, for extended and safer dives. To be continued...It appears that the depth ratings of the sensor are very conservative, which is to be expected for this kind of 'life supporting' equipment. Abbott surely won't take the risk of guaranteeing extreme operating depths, especially for the small customer base of scuba diving type 1 diabetics, even if their sensors appear to handle the pressure.</blockquote>
