Apera PH20 vs PH60

Researched by Johnny Alto · last updated July 27, 2026

Short answer: For most buyers, the Apera PH60 is the better pick over the Apera PH20. For anyone who tests pH regularly the PH60 is the better long-term buy.

Top pick

Apera PH60

For anyone who tests pH regularly the PH60 is the better long-term buy. It reads to a tighter tolerance than the PH20 and its probe is a screw-in replaceable type, so when the electrode wears out you swap the probe instead of the whole meter. That replaceable probe makes it cheaper to own over time and is why serious growers and brewers pick it.

How this guide was made: I don't own every product I write about, and I won't pretend otherwise. Unlike the hands-on reviews elsewhere on this site, this is a research pick, synthesized from hydroponics and homebrew communities, and verified buyer reviews. It reflects the community's consensus, not my own testing. See how we research our picks →

Both are Apera's popular pocket pH testers, and the choice is about how much accuracy and durability you need. The PH20 is the affordable entry pen; the PH60 steps up with a replaceable probe and tighter tolerance. Here is how they split.

Apera PH60 vs Apera PH20: what is the difference?

Pick	Product	Why it makes the list
Top pick	Apera PH60	For anyone who tests pH regularly the PH60 is the better long-term buy.
Entry pen	Apera PH20	Pick the PH20 to save money if you test occasionally and do not need a replaceable probe. It is a solid, accurate-enough pocket pen for casual use; the trade-off is that its probe is not user-replaceable the same way, so the whole pen is the consumable.

Which one should you buy?

The two are close, so the choice comes down to a few things: replaceable probe, accuracy, use frequency, and both waterproof. Here is how they split.

Replaceable probe: the PH60's screw-in probe saves the whole meter when it wears.
Accuracy: the PH60 reads a touch tighter than the PH20.
Use frequency: frequent testers save money long-term with the PH60; the PH20 suits casual use.
Both waterproof: either survives around tanks and reservoirs.
