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. ## Frequently Bought Together - Bluelab PROBPH pH Probe for Water, Replacement Electrode for Meter, Monitor, and Controller with Easy Calibration, Tool for Hydroponic System and Indoor Plant Grow - Bluelab pH 4.0 & 7.0 Calibration Solution Kit - pH Meter & pH Pen Calibration for Balanced Nutrient Solution NIST Traceable | Hydroponics, Gardening & Growing Tents (500 ml/ 16.9 Fl Oz Each) - Bluelab STSOL120 KCL Storage Solution 120ml pH Probe and Pen, Maintain Meters Used for Water, Soil, and Hydroponic System or Indoor Plant Grow White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/5640945-probph-ph-probe-for-water-replacement-electrode-for-meter-monitor](https://www.desertcart.pe/products/5640945-probph-ph-probe-for-water-replacement-electrode-for-meter-monitor) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-10-04*
