Apex Salinity Probe Replacement Options

[A;exr54]

Does anyone have any salinity probe replacement options for the Neptune Apex, which is not from Neptune?
Mine is going on a couple years old and has started acting up recently (with no stray voltage).

Neptune stuff seems to always have a large markup on the prices, considering what you get. Was wondering if any other salinity probe manufacturer can be recommended to be used with the Apex controller?
Or is it just best to bite the bullet and get the Neptune salinity probe?

You can use any double junction pH probe as the connection is universal, but you will likely find the markup from neptune is actually not that significant. pH probes look deceivingly simple, but there is actually a fair bit of complexity and delicacy to their construction so they aren’t as cheap as they may appear.

Think he is asking about the salinity probe.

I don't know what their cord is like. That will determine what can be used.

Ah, yes. Sorry I misread.

There is a whole thread on this but you are better off just biting the bullet and buying a neptune one so you don't have to solder a connector as no one knows the pinout anyway.

Salinity Probes that work with the Apex

Does anyone know if there is a cheaper solution for the salinity probes? The only ones I have seen have been in the $120 range and the Neptune salinity probe has bad reviews. Any info on cheaper or even just better probes for the price is much appreciated. Thanks.

Yes we did figure out the pinout. I've been using a pasco probe for about a year with no issues. To the OP, read through the thread, a few of us got around the proprietary crap from Neptune.

can you provide the link to the pinout ? Thanks

Link to probe?

Again, the info is in the thread. Requires some diy. Start @ post #58.
