Got this PH tester ordered......anyone ever used it? Opinions?

Been using just the drops for a few years now. Just something about subjective test results that I'm not really in love with. It's like I don't quite trust myself to interpret whether there's just the slightest hint of orange, or if it's still just piss yellow. I seem to have some odd mental block with differentiating between slight color variations, going all the way back to my time setting color on printing presses.

I don't have an interior designer's eye for color but it's pretty easy to consistently get within a tenth of actual pH with a little practice.

A quick example with GH drops:


In my experience, 6.0 is yellow, above gets progressively green, below gets progressively red.

In my experience, 6.0 is yellow, above gets progressively green, below gets progressively red.

To me, your 6.1 looks tinged with red, which I'd interpret as just below 6 based on the color key printed on the bottle. Maybe an issue of lighting and/or monitor settings. The plan is to keep using drops for large adjustments and the meter for fine tuning, assuming it arrives functional.

I'm gonna be honest. I don't test the EC or tds when I hydro, I just look at the plants and add it subtract accordingly. That being said I have the Apera PH60 just the ph meter and I have had it since '21... I definitely don't store it right, and treat it pretty poorly. It's still calibrated perfectly and reads perfectly and I only did the initial calibration once. The probe has gone dry a few times and even grew algae on it once. Cleaned it off and good as new 10/10 have zero bad things to say about apera

I've found the idea range is as effective as a specific number. Between 5.7 and 6.4, or yellow with a touch of orange to a touch of green works for me.

I get that it's not for everyone, but the more I KISS the better everything seems to work out.

We're not building rockets but just growing a weed.
Elon Egotist could use some hints here since he's good a blowing up his junk lol!!!
