pH tester instrument, or test kit?

As the cheapest electronic nute analyzer ive seen is north of $500 it sure makes the $10 paper kit seem much more reasonable don't it.
bluelab truncheon nutrient meters are great. accurate, very durable i use mine as a stir stick among other things that should break it. the one i'm on now is over 3 years old. these have been on the market for well over a decade and stood the test of time.
the simplest most durable meter i have encountered. it measures in ec, ppm ecx500, ppm ecx700 and cf. takes aa batteries.they are about a hundred bucks online though a local hydro shop should'nt charge more than $80. spending this kinda money really depends on how often u need to test nutes as in if ur making nutes multiple times a week i would spend the money well worth it.once a week or less prolly not. personally i like to have more control with nutes so i spend the money.
almost forgot they never need calibrating either, not out of the box not ever.
and no i'm not affiliated, just amazed when i find a product this simple works great and last a long time.
ok i just looked at mine and it says its guaranteed for five years on the side of it.
on the topic of dipstick ph meters, on the other hand, rarely last more than a year and need frequent calibrating. ive had at least 20 of them in three or four different brands in the last decade. (yet i still buy a new pos when they break) one should always keep the paper or drops kit. for when the digi takes a crap.
my two cents

Those truncheons are epic, the company owners still have the original model, over 10 years old and it still comes out on point.
I am very leary of most pH soil spike probes and homescale nutrient tests. They make pH pens look accurate
I would avoid Rapitest like they were peddling the plague. Not to sound like a dick (too late), but it's like HP22 said, low, ideal, high? What kind of system of measurement is that.

Neither as I grow with the soil food web and pH is irrelevant.Roguejim said:
Why do you need to check the pH?
Only if you are growing without soilpwb said:
Good to hear. There is so much misinformation out there so that everyone thinks they have to know the pH and the ppm and NPK numbers. Too many people listen to what the misinformed guy at the hydro shop recommends.Roguejim said:
Does anyone have experience with the cheap litmus paper you can buy on Fleabay?
(My home-brew soil is working fine for adult plants, but causes young seedlings to yellow out just as they are growing their first leaves. Transplanting them to ocean forest reversed the yellowing and got them growing well, so I'm wondering if the PH of my mix is a bit wacky.)
