Is there a way to change the values I calibrate to? I only have available pH 4 and pH 9 calibration solutions from all of the LFS in the area. I could order the pH 7 and pH 10 calibration solutions, but then I'd have to order the big bottle.
When I finish the pH calibration and leave the probe in the 10.0 solution the controller shows the pH @ 9.87 (which is close enough). But when when I remove the probe from the 10.0 solution and put it in my sump the reading on the controller jumped to 20.21. I put the probe back in the 10.0 solution and the display now reads 19.43. There is no way the pH in my tank is that high. I tested with a Salifert pH test and it shows 8.3
Rebooting the controller doesn't make any difference. I've repeated the calibration 4 times now with the same results.
I've only had the controller setup for just over a week now and my probe is new and never been exposed to air.
Calibrated to pH 4(244, adjusted to 544 via phone app) and pH 10(840, don't know what to adjust to since I can only go to 1024). Been playing with the numbers and I can't really find my sweet spot. It's read from 6.6 to 8.9. The only other way to check pH is a redsea kit, showing 7.8. What am I doing wrong? Adjusting all from the phone app.
I let the probe sit in the solutions roughly 10 min (I was worried about the temp variations so I cut it down a little), rinsed between solutions also.

hi everyone!
I am a bit slow thinking and i don't get it
so i got Ph9 and PH 7 from Dupla because nobody sells 10, i was looking all around australia and nothing
with 10 calibration...
so if anyone knows how to setup with 9?
7 is all good but 9
sorry for the silly question and thanks heaps in advance.
Just go ahead and go through the calibration with 7 and 9.
Write down the numbers you are getting on the calibration process.
It's just simple interpolation.
Post those numbers and I'll help you with that.
i haven't calibrated it but i did put in the water just for test and it's giving me 7.9 at night 8.1 all morning.
i think is more or less accurate, so i will wait till receive the 10 ph from overseas.
thanks a lot.
hola gente necesito ayuda me estoy volviendo loco no puedo calibrar la zonda de ph
primero pongo la zonda en agua
entro al menu calibrar ph
pongo la zonda en el ph 7
lo dejo unos 3 o 4 minutos
luego enjuago la zonda en agua
la pongo en la zonda 10
espero unos 3 o 4 minutos
Si puedes tomar nota de los resultados cuando lo pones en Ph 7 y despues los resultados con Ph 10
una vez los tengas postealos por aqui.
Yo lo que no hice es no darle al okay, le di a cancelar y luego lo programe en la memoria via wifi.
De todos modos que resultados te da?
saludos.
probe la zonda en otro medidor de ph y tira cualquier cosa, asi que supongo que el problema es la zonda... me voy a comprar otra zonda y probare a ver si con eso sale andando.
Le puedes mandar un PM a Roberto, el te manda una zonda nueva.
Tus números no se miran bien, el pH 10 usualmente esta en los 8xx.
No te olvides de sacar el enchufe para acer un reset.
