## Questions & Answers

**Q: Why should I choose Bluelab's pH probe?**
A: The quality of the probe. 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.
