GHL offers a variety of products for monitoring conductivity (salinity) and pH in saltwater aquariums, primarily through its ProfiLux aquarium controller system. There is no single "combo module" product name; rather, these functions are typically integrated into the main controller unit or provided via expansion cards and separate, high-quality sensors. 

GHL Conductivity & pH Solutions

The main components for GHL's measurement system are:

  • ProfiLux Controllers: The central hub (e.g., ProfiLux 4) has built-in inputs for pH, conductivity, and temperature sensors, which are galvanically isolated to prevent electrical interference. The conductivity input is adjustable for either freshwater or saltwater ranges (0-100 mS).
  • Expansion Cards (PLM - ProfiLux Mini): For systems needing additional inputs or specific configurations, GHL offers expansion cards. Examples include:
    • PLM-CondS-pH: Provides one galvanically isolated input each for conductivity and pH.
    • PLM-pH/Redox-Cond: Offers switchable inputs for either pH/Redox and conductivity sensors.
  • Sensors (Electrodes): High-quality, laboratory-grade sensors with BNC connections and extra-long 3-meter cables are available for both pH and conductivity measurements. The platinum conductivity electrode is suitable for both fresh and saltwater environments.
  • Calibration Fluids: GHL provides specific calibration fluids (e.g., pH 7 & 9 for saltwater, and 50 mS for conductivity) to ensure accuracy. 

Key Features

  • Accuracy and Reliability: GHL systems are known for their laboratory-grade measurement accuracy and robust design.
  • Galvanic Isolation: All sensors are galvanically isolated, allowing them to operate in parallel without electrical interference, a common issue in other systems.
  • Comprehensive Control: The system allows users to not only monitor parameters but also set up automated actions (e.g., controlling a dosing pump or powerheads) based on the readings.
  • Remote Monitoring: The ProfiLux controllers offer various connectivity options, including Wi-Fi and cloud access, allowing users to monitor their aquarium remotely via the GHL Connect app or a web browser.
