What is Reddit's opinion of Apera Instruments Premium-Series PH60S Food pH Pocket Tester Kit, Swiss Spear pH Electrode, ±0.01 pH Accuracy, -2.00-16.00 pH Range (AI313)?

From 3.5 billion Reddit comments

This is the one I always recommend. It’s on the expensive side, but having accurate monitoring of my grow helps me maximize your results given the amount of money I have sunk into this hobby. I went through a few cheaper ones didn’t last or hold calibration. This one keeps calibration for months. I check weekly with calibration fluid so I know it’s accurate. It also has the soil probe so you can test your soil pH without having to do a soil slurry.

I use this one. Skip the cheap ones.

Aphera PH60

Definitely Apera. This one if you have the means. It has the soil probe for checking soil and mine stays within specs for months at a time.

I believe Apera PH60S is the model I have.

I have this one expensive but holds calibration well and you can easily pH your soil with it - no need to do a soil slurry.
