| Re: Cells....
You will frequently find variations in cell MV. This will be the case even from cells that are coming from a new batch. If you can get a calibration and then close to 1.6 PO2 on a 20 foot flush with a reasonable response time, you should still be good to go.
When you get to a year, the smart move is to change even if they are reading well still. However, you might want to consider changing one in month 11 and one in month 12 out of the two that you have there. This will lessen the chance of putting two bad cells in at the same time.
BTW, as you will find, there will be a spread between cells after a while during the dive. So long as the spread is not very big, that is normal. Cells are among the weakest link in the rebreather equipment. |
