Delivered better than I expected! I have 6 different pricey pH units. My main ones are the bluelab guardian. The pH probes made by bluelab are $80-100 each, and are supposed to last 18months….but it’s more like 4-6 months….these not only work perfectly with the bluelab guardian, but they are 80% cheaper …AND they were actually slightly more accurate than the bluelab ones after calibrating. Stop wasting money on Bluelab replacement probes and just buy a ton of these.

L’ho comprato poiché il tecnico della piscina mi aveva chiesto 150€ per cambiare la mia ormai a fine vita. Ad oggi dopo una settimana di utilizzo sembra funzionare perfettamente. Non so quanto sarà la durata di questo prodotto ma per il prezzo che ha anche se durasse solo 6 mesi converrebbe a prescindere di più che spendere 150€. Al momento la consiglierei

It's good. Enough sturdy and easy to use.

Replaced a bluelab probe with this, works great. It's accurate and has been checked with other meters as well as calibration fluid. Awesome price.

I like the fact that it fits my blulab ph meter. From 2001 none the less. I've yet tried to calibrate the probe, but I suspect I won't have an issue.The probe itself looks well built, and 64.00 USD cheaper than the replacement blulab probe. (3 times)

Der Sensor funktioniert so wie er soll,bin völlig zufrieden.Und der Preis ist auch super.Habe den JBL Controller dafür muss man sich noch die Kalibrier Flüssigkeit besorgen.Hatte noch was da.Ich bin Zufrieden und werde es wieder kaufen.

En place depuis 2 saisons et fonctionnent tjs très bien. Juste à recalibrer à chaque saison comme toutes les sondes.

Snabb leverans och ett bra pris på en mycket exakt PH mätare.Lång sladd vilket underlättade monteringen enormt.

The ph probe for my aquarium would not calibrate anymore. I bought this as a replacement and hooked it up to my milwaukee ph controller. Works great and is accurate after calibrating it.

Fraction of the price as blue labs and works the same and is more durable. Win win.

These were attempted to be used on a Bluelab gaurdian and monitor. Calibrated each twice per instructions while also calibrating other meters.Meters calibrated fine, but this garbage never got closer being .3 and .6 off no matter what I did.Contacted factory. What a joke! I sent these clownss a youtube video showing exactly what their garbage was doing while also showing I was using a calibrated meter to check their probes. They now say they need to contact "engineering" to see what they want to do. They were probably laughing while they typed.Eventually THEY SUGGESTED I return them to amazon. Amazon shouldn't even sell this garbage. Returned and bought a Bluelab probe like I should have.

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.

Good product with great price，Since the ph electrode of my meter got broken, I bought this one right away and was amazed of its price. This holds calibrations well, gives accurate and stable readings. Works perfectly with my own meter. I am so happy for choosing this electrode!
