I've been using one of those cheap 10 dollar ph meters you get on amazon. I had 3 in fact. One was my gamer. it was never out of calibration. took readings fast. it was my go to. I recently dropped it in some water. dammit to hell. its dead. my backups just aren't the same. they'll do until I can find something better. what ph meter you guys use that you can recommend that are reliable?
 
My take...
Lab quality meters are nice, but they are just as susceptible to inaccuracy if not maintained.
I've found that the economy meters will stay accurate if you store the probe in KCl solution and check calibration periodically.
I use ph drops as a cross-reference if I think things don't make sense.
 
Im using an ADWA.
haven’t calibrated it for 3 years, think I never calibrated it🤔 And it’s perfecto my plants tell it all. And I can also use it in the soil for Ph testing. And this ADWA is waterproof also👍🏻
 
This is what I use:

Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH Accuracy

https://www.amazon.com/dp/B01ENFOIQ...abc_0EYJ0Y2P87CDSGXBS8QS?_encoding=UTF8&psc=1

It’s only for liquid solutions and not for soil, though this brand also makes those pH testing instruments as well. It’s a little on the pricier side but it is reliable, accurate, and has precision to two decimal places.
 
Howdy dustydundee, I ,like 9fingerleafs , use the tried and true pH litmus test strips (LabRat brand) they never fail, give good readings (range from 4.5 to 9.0), and never needs batteries! (LOL!).
 
What always bugged me about the test strips was the lack of precision. You can even interpret the color differently based on the ambient lighting in the room. Thoughts?
 
echdk3, some test strips say to read them right away, some need a few seconds before they can be compared to the standard color chart. The ambient light should not make any difference with the reading when comparing the strip to the standard color panels (unless there is no light at all! LOL!) and the brand that I have been using are accurate within their range by 0.25. The test strips cost from $0.10 to $0.15 each, depending on brands and where they are bought.
 
sounds like everyone has their own preferred method. i echo the same concerns on the test strips and how to interpret the readings. also tried the liquid test solutions, and same issue, the interpretation. I like the digital display on a meter, perhaps the meter isn't always right, but I can always tell what the meter is saying though! Once I get used to a meter though and calibrate it a few times, I know which way it tends to drift, so it becomes pretty predictable...if you don't drop the damn thing in water.
