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 water and soil (acid or alkaline) for precise up and down adjustment; General uses include coco coir blends, rockwool, growing tent, reservoir, water tank, and hydroponics - Designed for use with Bluelab Combo Meter, Bluelab Combo Meter Plus and Bluelab Multimedia pH Meter; 2 meter / 6.6 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 TDS pen, tester, and hydroponics tool for full garden nutrient monitoring in solution and soil; KIT INCLUDES: Cable, storage cap, probe holder, BNC connector, KCl solution in the cap, 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 | B07MDDXJ4J | | Best Sellers Rank | #16,811 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #18 in Lab pH Meters | | Date First Available | December 27, 2018 | | Item Weight | 2.4 ounces | | Item model number | PROBPHLEAP | | Manufacturer | Bluelab | | Product Dimensions | 6.8 x 1.5 x 1.5 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/718Npl7Q-iL.jpg) ## Available Options This product comes in different **Style** options. ## 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!.
