I know some of you have been waiting for these quite some time.
I have a very very limited quantity of these available at $149 each.
It comes with the following:

• Salinity Expansion Module
• Salinity Probe
• 12 VDC Power Supply

The libraries for this module is not yet fully developed.
I'll be working with Curt to get it added.
If you are interested, please PM me.

ohh, nice, but alas to rich for my blood, at this time.

Same here...maybe a group buy option would bring it down?

[rimai]

Yeah, that's the reason I have always been against investing so much time and effort into getting one of these out, but since there had some interest, I decided to just give it a shot.
I could sell just the module for $60, but it would be no good without the probe. The probe is what is really expensive.
They work by measuring the electrical conductivity through the water. So, the probe needs two metal leads that conduct very tiny amount of electricity through the water and they are made out of platinum to avoid corrosion, which unfortunately drives the price point to the upper side.

Hey Robert. Do you have any left and what's the status on the libs? At $149 I'm still considering buying one though a group buy would definitely sway me. Thanks.

The libraries .19 released from Curt contains the code for the Salinity Module.
Although, there is no calibration menu option made yet.
Calibration values can be manually registered within the code or internal memory easily though.

Did this ever go live? I don't see it in the shop for sale, and would like to eventually like to run this module if I end up buying a reef angel.

Thanks!!

[rimai]

Yes, I have made a very limited quantity of these and they were all sold.
I do plan on manufacturing some more in the very near future.

Hi Guys,

I ended up getting one of these bad boys, and have been very impressed with the results.
There was initially some problems with getting it up and running, but with some help from Roberto we were able to get it going.
If you pick one up (and i recommend one if you have the budget) try and install it in a place away from your heaters, as fluctuating temps in the water will impact the reading.

You will also need a custom main screen setup if you want to display the value there. Im using the following code on mine:

ConvertNumToString(SALtxt, ReefAngel.Params.Salinity, 10);
ReefAngel.LCD.DrawHugeNumbers(COLOR_LIMEGREEN, DefaultBGColor, 5, 55, SALtxt);

I'm not sure if its in the current release of the library's yet, but i needed to download the salinity module library's from Curt's github, and also the calibration code. I had really weird results until i loaded the calibration code.

If anyone needs a hand, feel free to give me a yell.

do you happen to have an iPhone and the app? I added support in but was never able to test on a live system since I was not one of the lucky few to get one

[mr_mojo02]

Nah, i don't have an iphone mate. Maybe someone else can jump in with their results?

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

[rimai]

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?

[rimai]

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.

[Deckoz2302]

Still have these available?

[rimai]

Yes, I have one more available.

[Deckoz2302]

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 :/

[rimai]

It's actually 12VDC with center positive.

[Deckoz2302]

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

[rimai]

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.

[Deckoz2302]

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

[jnicita]

Yes, I have one more available.

PM me please about this. Would like to know about 3rd run as well, thanks in advance.

[bluwinghawk]

do you have any in stock now i would like to get one please

[rimai]

No. I'll have some in about 3 weeks.
PM me if you would like to reserve yours.

[bluwinghawk]

lol im not allowed to pm yet but yes reserve one please and let me know when and how to pay thanks

[mason dixon]

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?
