Bluelab pH Probe
The Bluelab pH Probe is a genuine replacement electrode designed to restore the accuracy and performance of your Bluelab pH monitoring equipment. Compatible with the Bluelab Combo Meter, Bluelab pH Meter, and Bluelab Guardian Monitor, this high-quality replacement probe allows you to replace only the probe instead of purchasing an entirely new meter, saving both time and money.
Accurate pH measurement is one of the most important aspects of successful hydroponic and horticultural growing. Even when nutrient levels are correct, plants can only absorb essential elements efficiently if the nutrient solution remains within the correct pH range. A worn or damaged pH probe can produce inaccurate readings, leading to nutrient lockout, poor growth, and reduced yields.
Every pH probe contains a Potassium Chloride (KCl) solution that enables it to measure acidity and alkalinity. Over time, this solution gradually degrades through normal use, causing all pH probes to age and eventually require replacement. Regular maintenance, including keeping the probe tip moist and cleaning it approximately once a month, will help maximise the probe’s lifespan and maintain reliable performance.
The Bluelab pH Probe features a double junction reference system, providing improved contamination resistance and a significantly longer service life compared to many standard pH probes. The probe is also gel-filled and non-refillable, making it virtually maintenance-free apart from routine cleaning and correct storage.
Designed to deliver fast response times and dependable accuracy, the Bluelab pH Probe is trusted by commercial growers, hydroponic farmers, greenhouse operators, and home gardeners worldwide. Whether you’re managing a single reservoir or a large commercial nutrient system, replacing a worn probe helps ensure your pH measurements remain accurate and your plants continue to perform at their best.
