Description PH/ORP PROBE MODULE PM1 The PM1 probe module is just what you need if you want to monitor pH or ORP in your tank. And, there is an added bonus, you get an extra temperature port as well as six I/O switch inputs for use on ATO, feed buttons, or whatever else you may come up with. This module is perfect for someone that wants to add an additional pH or ORP port to their Apex System. Not all monitoring ports are created equal. Galvanic Isolation is key to getting accurate readings on pH, Temp, ORP, and Conductivity. Some controllers either do not do it well (they are still figuring it out) or possibly not at all. FEATURES OF THE PH/ORP MODULE INCLUDE: Monitor/Control pH or ORP, and temperature 6 digital inputs for float switches, water on floor sensors, pressure sensors, etc. Full datalogging support in Apex Base module Up to 240 AquaBus modules can be added to the Apex system Plug and Play.
