pH is a key parameter for maintaining a stable aquarium. Excessive fluctuations can directly impact corals, fish, and the entire microfauna. With the Neptune Systems dual-junction pH probe , monitoring becomes reliable and consistent. Its two-chamber technology acts as an additional barrier against impurities and contaminants in the water. This helps preserve the purity of the internal electrolyte and ensures accurate measurements over time .
Unlike single-junction models, this version significantly reduces the risk of clogging and premature wear. Readings remain consistent, even in demanding environments such as heavily supplemented reef aquariums. For aquarists concerned about the chemical stability of their tank, it's a safe and reassuring choice.
This Neptune Systems pH electrode is equipped with a standard BNC connector, making it compatible with the vast majority of monitors and controllers on the market. It works perfectly with Neptune Apex systems, as well as with other equipment that has a BNC input.
Its approximately 3-meter cable offers true installation freedom. The controller can be positioned remotely from the tank without compromising signal quality. Integration is quick and easy, requiring no complex procedures, simplifying the replacement of a worn probe or the addition of an extra monitoring point.
Thanks to its reinforced design, this dual-junction pH probe offers a longer lifespan than standard models. On average, replacement is recommended every 18 months , depending on usage conditions. This longevity reduces maintenance costs and ensures reliable long-term monitoring.
To maintain optimal accuracy, calibration is recommended every 60 to 90 days . This simple operation ensures consistent and usable readings. Calibration fluid is sold separately, allowing you to adapt maintenance to your tank's needs. Easy to clean and robust, this probe quickly becomes an essential part of the daily management of a demanding aquarium.
