thanks for the heads-up! i will keep an eye on it for sure.Be cautious of the Ti probes. I found that I would have to wipe them down ~once a week with alcohol pads to remove the passivation layer or they wouldn't respond. Then I finally (~1 year) had the low level probe leak internally I assume. I would have to remove it, blow it out then wipe it down. This was in an IM20 so coming around the corner to bubbles everywhere got to be a bit old. Last I looked they had discontinued these. When they work, they work great. As far as using these probes on an Apex, I don't know why you couldn't just run them through a BOB like a regular float switch. Makes me think about it, I might use my old ones for safety/HI-HI Level shutoffs.
