I have three aeroponic systems , I would like to install dependable PH monitors. I want to be able to see what the ph levels are without breaking out a PH test kit . Or buy a tester that I can dip into my aeroponic holding tank and test the ph in just a few seconds . From my under standing some monitors have to be recalibrated or are in the shop to be repaired . I don't want a monitor that isn't dependable . If any of you are using PH monitors , please suggest a trouble free monitor . I don't know how much a good monitor costs ?
I'm guessing you need one with a detachable probe you can leave in the reservoir? Good brand.. Portable Meters
Yes and dependability , Want a plug and play PH meter ,, with no hassles , I don't want to be sending the meter back for repairs or calibration ,, do they make PH meters like what I am describing ? In the end I need three PH meters . Thought about buying a meter that adds the PH up or down automatic . But I don't know if I trust one that much . As you said a meter that is in the reservoir . Do you own a PH meter like I am describing ?
