APERA INSTRUMENTS 201DJ-C Double-Junction Combination pH Electrode is ideal for long time consistent testing in turbid water solutions, such as wastewater, pools and spas, and environmental monitoring. Its double-junction structure prevents the probe from being clogged and contaminated during measurement. Measurement Range: 014 pH, 080?C (32176?F); Housing: Polycarbonate; Junction: Double Ceramic; Reference Electrode: Ag/AgCl; Connector: BNC; Size: ø12 160 mm; Cable: 3 Ft. Not suitable for testing in low-ion concentration solutions (eg: deionized water or distilled water), strong base solutions (pH>12), highly corrosive liquid, or for continuous testing in high temperature solutions (>140?F). Compatible with any pH meters that use BNC connectors. Temperature sensor is not built-in. Users need to have a separate temperature probe to enable ATC or manually input temperature to complete temperature compensation

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.

Works as expected, quick response time and accurate readings. Great price for this probe.

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.

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.

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。

Installed this unit and it was reading 1 full point below what my ph pen was testing. CAlibrated oin 7.0-10.0 solution and it would only read 9.1. Never worked out of the box.
