Hi all,
I have a milwaukee mw 100 ph meter and I'm not sure if its working right
I cleaned and calibrated the meter, but still the same problem
It can read the calibration solution with no problems, if I use the 7.0 solution, it shows 7.0 and the same for the 4.0 solution
If I make a nutrient solution with ph 5.8, the ph drops after 30 min to 5.5, if I stir the water, he goes back to 5.8, if I dont move the electrode it goes down to 5.5, stiring and it jumps to 5.8
What do you think? Should I buy a new one?
The meter has a accuracy of + - 0.2
Greetings
