Neptune Systems - pH Double Junction Probe is available for pre-order – please confirm stock before ordering!
The Neptune Systems pH Double Junction Probe is a high-quality, lab-grade sensor designed for continuous and reliable monitoring of pH in saltwater and freshwater aquarium systems. Built for compatibility with Apex controllers and expansion modules like the PM1, this double junction probe offers enhanced durability, longer service life, and greater resistance to contamination compared to standard single-junction probes.
Essential for maintaining stable water chemistry, the probe ensures accurate real-time pH readings—critical for coral health, nutrient uptake, and biological balance in reef systems. Its double junction construction helps prevent internal reference solution degradation, making it ideal for environments where organic or mineral buildup may occur.
Key Features:
Double junction design for extended probe life and improved accuracy
Continuously monitors pH in real time when connected to Apex-compatible modules
Greater resistance to contamination and fouling than single junction probes
Factory calibrated and ready to use with minimal setup
Compatible with Apex PM1, PM2, and other Neptune Systems interfaces
Suitable for both saltwater and freshwater aquariums
With the Neptune Systems pH Double Junction Probe, aquarists gain peace of mind and precision control over one of the most critical parameters in aquarium chemistry—ensuring stability and success in even the most demanding marine environments.
