Why should I choose the Bluelab pH pen over others?

The probe quality. Highly accurate, compensates for temp & is fast to a stable reading. It's a double junction probe, so it's durable. And it's full of thoughtful touches (the ring on top, the storage cap, the calibration indicator to name a few).

Other pens come with a hard carry case & calibration solutions in plastic bottles. Yours does not. Why is that?

Great question. We have made the deliberate choice to make our packaging as sustainable as possible. To that end, our packaging is all fully recyclable, with no hard plastics or styrofoam inserts.

How does Bluelab make calibration super easy?

Calibrating is an easy & fast process! Each pen includes calibration solutions & clear instructions. A check mark appears when the pen is calibrated. When the pen loses calibration, the check mark disappears, informing you it's time to recalibrate.

I sometimes see a white crust built up on the end of the pen. What is this?

This is very common in pH meters & is nothing to worry about. The storage solution used to hydrate your pen (and extend its longevity) is potassium salt, which sometimes dries as a white crust on your probe. Simply rinse this away under water.

There's a lot here about growing plants. Can I use the Bluelab pH pen for other applications?

Absolutely! Our pen is a critical tool for anyone who is seeking precision and consistency in the pH of their liquid solution. Our pen is used by leading brewers, vintners, wastewater technicians, and scientists in the field, just to name a few.

Fast and accurate.

Excellent, PH meter. From some of the reviews. I assume they don’t read the directions. I would suggest getting the combo pack that comes with KCI solution and calibration solution. Inside the cap is a tiny little sponge. Make sure you don’t toss that out thinking it’s the KCI solution hardened. If you notice salt residue on your probe when you open it up, simply follow the directions and make sure you soak it for 24 hours in the supplied KCI solution before calibrating and using. My probe was completely dry and rewet no problem. It reads very fast, which is convenient.

Prodotto eccezionale, preciso e super affidabile! ⭐⭐⭐⭐⭐ Il tester è arrivato in tempi brevi, perfettamente sigillato e conforme alla descrizione. All'apertura ho notato che la sondina di vetro era un po' asciutta, ma è bastato seguire alla lettera le istruzioni incluse per idratarla nuovamente e rimetterla a nuovo. Ho eseguito la calibrazione ed è andata subito a buon fine al primo colpo: la sonda si è rigenerata alla perfezione! Ho fatto tutti i contro-test di verifica ed è di una facilità, precisione e velocità incredibili. Un prodotto bellissimo che consiglio a tutti i coltivatori che cercano la massima precisione per l'acqua delle proprie piante. Bluelab è una garanzia.. venditore eccezionale
