Highly accurate but priced a bit steep for many ordinary gardeners - If you are looking for lab quality and extreme accuracy look no further. All blue lab products that I have tested which include their combo meter, soil ph pen, and the guardian meter have all performed excellent. The ph probes must be kept clean and submerged in a solution (I use tap water that is frequently changed out after each use). To keep the probes lasting you must keep proper maintenance and always be sure to recalibrate one to two times a month for best results. Calibrate in ph 7.0 solution first and follow it up with 4.0 until your ph probe has a check mark in which it should now be perfectly calibrated and accurate. Be careful not to drop your ph probe as they can be fragile that most likely would resulting in accurate readings or cracked glass. Review: Muy buen sensor - Muy bueno.

Our probe is built with accuracy & longevity in mind, with a polycarbonate housing for long-lasting strength, a double junction to reduce reference contamination, and a fast sensor response for quick & accurate measurements. **Q: Is it waterproof?** A: Yes! The Bluelab ph Probe is fully waterproof, not just water resistant. **Q: Is it compatible with all pH meters?** A: Our probe will work with all Bluelab meters, monitors and controllers and is also compatible with any meter that has a BNC connector. **Q: What all is included?** A: The probe is on a 2 meter (6.5 ft) cable, allowing access to hard-to-reach locations. It has a storage cap that holds KCl storage solution to keep your probe well hydrated. And there is a suction cup to affix the probe to the side of a reservoir. **Q: I sometimes see a white crust built up on the end of the pH Pen. What is this?** A: This is very common in pH probes & is nothing to worry about. The storage solution used to hydrate the probe (and extend its longevity) is potassium salt, which sometimes dries as a a white crust on your probe. Simply rinse this away under water. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Extreme accuracy comes at a price but well worth it. *by Y***R on July 29, 2019* I have been using bluelab products for over eight years.
