Don't forget to buy the storage solution - FYI Review: Extreme accuracy comes at a price but well worth it. - I have been using bluelab products for over eight years. 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. ## Features - Measures pH in nutrient solution (acid or alkaline) for precise up and down adjustment and is used with meters; General uses include growing tent, reservoir, water tank, and hydroponics - 2 meter / 6.56 foot standard cable, easy calibration, fully waterproof including cable joint, easy to clean and maintain - Double junction probe has a longer lifespan compared to standard probes due to less contamination and is more accurate and reliable than comparable pens, test strips, drops, and more - Combine with Bluelab tester, meter and other controllers for full garden nutrinets monitoring in water and soil; KIT INCLUDES: Cable, probe holder, storage cap, BNC connector, probe care kit is sold separately - Supplied by Bluelab, the industry leader in hydroponic testing equipment, built for growers; 6-Month Limited Warranty with proof of purchase ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005AXSNP6 | | Best Sellers Rank | #29,519 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #30 in Lab pH Meters | | Date First Available | February 20, 2011 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.96 ounces | | Item model number | BLU24102 | | Manufacturer | Bluelab Corporation Limited - Import (NZ) | | Product Dimensions | 6.1 x 0.86 x 0.86 inches | ## Images ![Bluelab PROBPH pH Probe for Water, Replacement Electrode for Meter, Monitor, and Controller with Easy Calibration, Tool for Hydroponic System and Indoor Plant Grow - Image 1](https://m.media-amazon.com/images/I/71xgrk2BiRL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Accurate and functional *by N***O on October 8, 2025* Worked perfectly and accurate.

Fantastic unit, holds calibration for months at a time when taken care of properly. The first Probe lasted most of a year, I bought a replacement from a local shop and was surprised that it was a different Probe than the factory one. It was plastic as opposed to glass. It did not keep calibrated at all. I complained to the shop and was told they didn't understand what my problem was. The PH tester module isn't cheap $230ish dollars, I did not want to have to buy another complete unit. I was hoping that I could replace the probe with something resembling the factory unit. When I got the one I ordered from Amazon I was very happy. It is the exact same as the factory probe! It is made out of glass! It holds calibration! Once again Amazon saves the day!. Thank you. ## 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.in/products/5640945-bluelab-probph-ph-probe-for-water-replacement-electrode-for-meter](https://www.desertcart.in/products/5640945-bluelab-probph-ph-probe-for-water-replacement-electrode-for-meter) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-27*
