I'm going to have to go strongly on the side of not replacing all of them at once either. The 'bad batch' problem occurs much too frequently, and it was a regular occurance with the Teledynes... and I've had one such occurance with the AI's.
Hello n2diving, it's my understanding that the Prism O2 sensors, which are made by AI, are shipped from the manufacturer as a mixed batch, meaning the orders are made up of sensors from different manufacture dates. Maybe this was only done at the request of SMI, but it seems like a sensible proceedure and maybe other wholesalers of AI sensors should ask them to do the same... -Andy
