problem ph
Re: problem ph
how do I make the count of those numbers for ph 4 and 7?
Re: problem ph
The numbers you see during calibration are the raw 8-bit ADC value that Arduino has internally.
It's a value that goes from 0 to 1023.
ph 7 is around 540 in that range and ph10 is around 830. So, for ph4, you will be looking at somewhere around 250 if my math is correct....

Re: problem ph
hello I tried to calibrate the pH and after an hour in kh 4 mi marks the maximum number of controller 86 and kh 7-329
Re: problem ph
Where should I put these two lines?
ReefAngel.PH Min = 250;
ReefAngel.PHMax = 512?
ReefAngel.PH Min = 250;
ReefAngel.PHMax = 512?
Re: problem ph
You don't need those lines.
Just go through calibration and make sure you pick ph4 and ph7 as reference or it won't work.

Re: problem ph
I have to cancel these lines?
Re: problem ph
when time for calibration ph 4 and 7 in total?
Re: problem ph
there is a test to be done to see if the probe is to be changed?
Re: problem ph
Calibrate and place the probe into the calibration fluids you used in the calibration.
It should show their value.

Re: problem ph
yes, I've done 100 times when I put it in the solution pH 4 I get kind ph 4:40

Explane please

Re: problem ph
Maybe you ought to try the 7 and 10 if 4 and 7 is not working for you.
Someone else did it with 4 and 7 and got it to work just fine.

Re: problem ph
I need the probe 4 and 7 because I have to connect the reactor elletrovalvola
Re: problem ph
Linearity of pH probe is pretty good within all ranges that we use:

Re: problem ph
Good morning and Merry Christmas to everyone today I calibrated the probe again and me with solution 4 = 4.16 and 7 = 7.02 solution over so I can not right?
I need to update some library?

Re: problem ph
Looks pretty good.
You just need to let the probes stabilize a little more before you complete and also make sure that the solutions are the same temperature as your tank water.
You will never get exact measurements. This is not a scientific device nor the probe is scientific/lab grade.
Personally, your calibration is fine as it is.
It has a .16 deviation on a 3 ph span.
In the range of pH you are going to be working on, it would mean something like 0.025 ph deviation
I don't think your reactor can even notice this minute difference.
i more bubble inside your reactor can cause more deviation than that...
Just my 2 cents, but if you really want to push to get it down to perfect calibration, please go ahead.

Re: problem ph
good day yesterday, the solenoid valve is always on, and marks on the reef angel ph 680 up and down, now I have removed the pH probe from the reactor and put into solution pH 4 and pH 6.60 tells me, I try to recalibrate and idem, which I do?
with the reef angel...

Re: problem ph
with ph 4 290 and ph 7 310, the pH probe is rechargeable?, what product I could use to clean it?
Re: problem ph
so how should I do? 12 months that have the probe
R: problem ph
No i dont have other prob
