Long Body pH Electrode with BNC Socket Probe 300cm Cable 0-14pH for pH Meter, pH Controller pH Device Economical Sensor

It works, and that's about all you need to know. They don't last forever but they are cheap (last one was 5 y.o.). Note they work great with a Digital Aquatics Reef Keeper SL1 module (now out of business).

I used it to replace the probe on my Bluelab Guardian with no issues. Calibrated with no problem and has been working for a few months now. Quick accurate readings is all I can ask for and so far this thing is delivering at a fraction of the cost of Bluelabs probe. I'll update with any issues.

Purchased as a replacement probe for my BlueLabs device. The electrode connected and calibrated perfectly and is giving consistent accurate readings. I don't know what the longevity will be, but at a fraction of the cost for a Bluelabs replacement, even if it lasts 1/2 as long it's still worth it.

For the money these probes work very good completely submersed. I calibrate every 10 days. I normally get 60 days use before latency in readings begins to be a problem. At about the 60 day marek the probes takes 2-3 times longer to report accurate PH. Specifically PH values between 5.5-6.0. If you are running auto PH systems this can be a problem. As the reservoir gets low and the PH swings high and the dosser dumps PH down to correct and that throws out the PH during feeding. When this occurs, time to replace.

It worked great if you’re testing and one of your test shows error just press on and come back to it. Once it gets a different foundation of the other calibrating test it should register.

After multiple calibration, probe readings bounce around every second until finally reading 15 and stopping. I do not recommend.

I have been tinkering with DIY pH projects now for quite some time. I have tried 3 different probes now and this probe out performs all of them so far. I am using this probe with a sensor board from AnyLeaf. It is compatible with that board and any that have a BNC style connection. I would recommend this kit to anyone looking for a replacement. The temperature readings are spot on as well as pH. I only had to calibrate this one time and it worked. I have tried others that would not hold calibration very well, and this one holds flawlessly. I am using this in a hydroponics system where I monitor pH conditions 24 x 7. I get very accurate real time readings with this unit.

Seems to also function well with HM100 and HM200 fascist

📦 Versand Der Versand verlief schnell und zuverlässig. Die Sendungsverfolgung war transparent und die Sonde kam gut geschützt bei uns an. 🔬 Produkt Unsere bisherige pH-Sonde hatte nach mehreren Jahren zuverlässiger Nutzung an unserem Poolausgedient, daher musste Ersatz her. Die originale Ersatzsonde war mir preislich zu hoch, weshalb ich mich für diese Alternative entschieden habe. Die Elektrode macht einen soliden Eindruck, das ca. 300 cm lange Kabel bietet ausreichend Flexibilität bei der Installation und der Anschluss über die BNC-Buchse funktionierte problemlos. Nach der Kalibrierung lieferte die Sonde stabile und plausible Messwerte. ✅ Fazit Nach mehreren Wochen im Dauereinsatz arbeitet die pH-Elektrode zuverlässig und ohne Auffälligkeiten. Für den günstigen Preis erhält man eine solide Sonde, die ihren Zweck erfüllt. Wer eine wirtschaftliche Alternative zu teuren Original-Ersatzteilen sucht, macht hier aus meiner Sicht nichts falsch.

Una soluzione che cercavo da tempo, sostituito con uno molto più costoso e fa egregiamente il suo lavoro

Cost effective and as advertised.

Installée et calibrée sans la moindre difficulté, fonctionne parfaitement jusqu'ici, à voir sur la durée mais à 15€ au lieu de 87...

When it came it didn't fit. I couldn't get through to the supplier to replace. Then when I eventually coil. I was told it is too late.
