I'm after some suggestions as to which pH test strips to get. (Already have a pen but want to try strips now)
It seems there's a wide variety of different chemical detectors used in pH strips, and some are "for urine/saliva only, not for water testing", and then there are "Low Ion" ones - "Lo Ion Kits give accurate readings in dilute or unbuffered solutions where ""dip and read"" tests may read low."
I have no idea if I need low ion kit or not! But their 5.0-9.0 one would seem suitable and does come as test strips. I just use tap water, which has no detectable EC on my bluelab truncheon, if that matters.
Does anyone have any suggestions - specifically for testing hydroponic reservoirs?
At this stage I'm considering these from the pHydrion range (no idea how good they are but were dominant in my googles):
- Hydrion Lo Ion Dispenser 5.0-9.0
- Hydrion S/R Dispenser 5.0-9.0
- Hydrion Test Paper pH 5.5-8.0 *it seems at least one version of the 5.5-8 is for urine but not water
- Hydrion MicroFine Disp. 4.9-6.9
I'm getting a separate general purpose 0-14 one too, but for this thread i'm looking for a more high-resolution (.2 to .5 resolution) one for hydro reservoirs, ~4-9ish
