My question is what kind of cost to build one? Is it actually cheaper to build your own? Whats the time put in? Difficulty rating?
How does this compare to say the alkatronic which sells for about $900 buck a roos?!
This is very cool and awesome job!
The difficulty ratings of this device is "not for the faint-hearted", i.e. quite difficult.My question is what kind of cost to build one? Is it actually cheaper to build your own? Whats the time put in? Difficulty rating?

Looks very nice! What kind of PH probe are you using? I don't think super-accurate PH probe is needed for Alk monitor - it just needs to be within +/- 0.1 PH accuracy, however looking at the colour of PH probe it looks to me like one of the cheaper ones. You may want to replace it with a slightly more expensive one - this will provide calibration stability!hello borat
I found that we are doing the same thing.
i came from china.and i made one kh tester by arduino,but that was not good. So i made aonther one by a rasoberry pi with html. Exactly i was finished the main work just yesterday.
i use 2 DC moto with water level switch,and one Geared motor for acid. Photoelectric counting switch to cpunt how many drops of acid was added.
the case made by Acrylic,and the titration chambe made by 3D printing.
it's has been running for half day,Looks good so far.
My ph probe is dfrobot ph sensor kit v2,dfrobot has some more expensive ph sensor,i will try it.Thanks for your advice!Looks very nice! What kind of PH probe are you using?

Understood, this kit has an improved PH board with built-in voltage regulator but I think it still has a cheap PH probe. Cheap does not always mean bad - but keep an eye on it and if it drifts - you know where to look!My ph probe is dfrobot ph sensor kit v2,dfrobot has some more expensive ph sensor,i will try it.Thanks for your advice!
ok, i will buy a better PH probe tomorrow.Understood, this kit has an improved PH board with built-in voltage regulator but I think it still has a cheap PH probe. Cheap does not always mean bad - but keep an eye on it and if it drifts - you know where to look!
In my DIY setup I am utilising 4 PH boards from DF robot - all boards are v1.2... however I do not use these blue probes - all 4 probes that came with the PH boards are sitting in the cupboard idle.
Why 4 board? I use 1 in Alk monitor and 3 more in my aquarium controller: 2 are controlling CaRx (primary and seconardy media chamber) and 1 more is for tank water monitoring..
i have now CaRx my tank is small,only 60x50,so maybe i need change both two PH probe.In my DIY setup I am utilising 4 PH boards from DF robot - all boards are v1.2... however I do not use these blue probes - all 4 probes that came with the PH boards are sitting in the cupboard idle.

Good night!r

dfrobot is a chinese company,i can buy v2 kit very easy with taobao,
good night Borat
Hello folks from US&A. Warm hello from a friendly nation of Kazakistan!
Please check out my video for a DIY Alkalinity monitor that I built myself!
Cheers,

Where do I insert my credit card information.....so all of you are very excited about having this piece of equipment (whether DIY's or, most likely, purchased).
Now let's consider the running cost of owning this piece of equipment. DIY version probably means your running cost are half of those commercially made, however still it's not that cheap:
- you probably need to replace the PH probe every 24 months, I use quality inexpensive probe that's £40 = $54. For commercially made devices it's definitely more expensive (double the cost)
- you will need reagents, each test at 10 DKH and 100ml reaction chamber will require 3.6ml of 0.1N hydrochloric acid. I run 7 tests a day (at 3 hour intervals), that's 25ml/day or 9L of acid a year. Here in the UK I can buy 5L of 0.1N hydrochloric acid for £31 (delivery is extra cost!), that's $!43, so a year's worth of reagest will set you back almost $100.
- you will need PH calibration solutions, no need to calibrate frequently, probably once a year would do - small thing a few US&A bucks..
- once every 2 years you would want to replace santoprene tubing, that's probably another $10
- you would probably want to amortise the cost of your equipment over, say 5 year period. Assuming you bought it for $700 - that's $140 a year cost (quarter as much if you DIY'd it instead - it will last longer than 5 year and is cheaper to build).
So overall the annual cost of running an alk monitor is about $250 a year. Still worth in my opinion (seiously - I can adjust my AlkX in real time ensuring no stress on corals).
