The best ones I tried as of yet
I use these pH electrodes in a machine that produces chorine solution from splitting salt water with electricity. So the environment is definitely corrosive even for plastics (over time). Electrode has been performing way more stably then a different brand that I used to buy here on amazon. So I really vouch for these right now, at least for my application. I don't even expect these to last more then a few months since they are constantly dipped in the concentrate, and this one is performing great.

I'd say this is probably a really nice EC sensor
I'd say this is probably a really nice EC sensor, except the item description is for the PH probe. I'd love to try their PH probe, but I keep getting sent their EC sensor sent by mistake. Since the ph probe is double junction and made by Apera, I'd imagine it is an excellent choice. I hope to be able to review their PH probe soon.

米国オハイヨ州の老舗医療機器メーカー。 精度と反応速度が素晴らしく、誤差は全くない。 見た目も高級感があり、コネクター根本の作りも本格なラボで使えるほど耐久性がある。 BNCコネクタを搭載する全てのpHモニターに接続可能。 コードの長さが3mと記載されているが、本品は1mしかないので注意。

Mi potenciómetro reconoce el electrodo sin problema y pude calibrarlo. Las lecturas son estables, por lo que a ese precio estoy muy satisfecho con la compra.
