Does not look right.
Is the glass bulb in the tip of the pH probe intact?

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.

544 for pH7 and 840 for pH10 seem correct numbers.

The issue is that those settings make my pH read ~6.6

Oh, one other thing. Doing through the phone, Client or any app will require you to reboot the controller after you save the numbers.

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.

cheers.

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 :shock: 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.
:)

cheers!

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.

Le puedes mandar un PM a Roberto, el te manda una zonda nueva.
Tus nĂºmeros no se miran bien, el pH 10 usualmente esta en los 8xx.
No te olvides de sacar el enchufe para acer un reset.
