I checked it and the reading shows up fine.
Although, there is a cosmetic error. It shows in the wrong decimal. It's supposed to be 35.0ppt and it's showing 0.350

aww lol I forgot I set it up for a specific gravity measurement like 1.025. I will fix in next update. Thanks

It's actually not specific gravity, but in actual salinity, which is measured by parts per thousand (ppt). The value in the XML will be usually 350. Simply divide it by 10 to get one decimal point and display it as 35.0 ppt.

Yea when I first added it in I was planning on doing a spot for Specific Gravity and one for the Raw Salinity measurement. Forgot to finish it up though.

At least you had some form working. I had a generic placeholder and didn't allow for parsing it properly thus causing the parser to fail. Mine is fixed now too. :)

How reliable are these probes? Something that needs to be replaced each year or more?

They are made of extremely thin platinum plates that do required replacement.
As with any other metal, there will always be corrosion, even though it is minimal.

On the 5v input, is center pin positive or negative? And how many mA is the unit as I have a 5v regulator circuit for my fans controller w/700mA and using 300 of it trying to jump off of that if I can instea[youtube][/youtube]d of buying a power supply. Let me know cause the manual doesn't state polarity or amperage. Thanks, I'm confused because the jack says 5v and the manual says 12v. And I didn't receive a power supply :/

It's actually 12VDC with center positive.

I just got the power supply in for the module, powered down the RA hooked it up - the ra continually resets over and over again....if I power cycle the controller sometimes the screen where the salinity readout is say 20*.64*86 the * are degree symbols. when it stays on and shows these symbols the controller is locked up joystick doesnt work. The PH probe and main temp sensor are in the overflow, second temp sensor is in one side of the sump, salinity probe is on opposite side of sump so it should be far enough away that the voltage from it isnt affecting it? uhh so confused

Probably internal memory not initialized.
What do you get when you browse http://myipaddress:2000/mi847 ?
Set initial value to 2550 using http://myipaddress:2000/mi847,2550
Let me know if this solves the problem.

That worked, and surprisingly I didn't need to calibrate its spot on sir.

Any idea on how often the probe needs to be replaced? What does that cost?

Does anyone use this in conjunction with a saltwater topoff system to keep the levels spot on?
