GHL ProfiLux 3.1Tex Aquarium Controller System

The GHL ProfiLux 3.1T ex is a high-end, professional-grade aquarium computer system, valued by both hobbyists and research institutions for its exceptional accuracy, reliability, and extensive control capabilities. 

Features:

• Integrated Ports: The 3.1T ex comes standard with built-in ports for essential sensors, including temperature, pH, and conductivity probes.
• Precision Monitoring: It provides highly accurate, real-time data monitoring, essential for maintaining stable and optimal aquatic environments.
• Extensive Expansion Options: The controller includes internal expansion slots, allowing users to add more functionality, such as additional probe inputs (e.g., a second pH or redox probe via an expansion card) and other specialized cards, without needing external modules.
• PC Connectivity: The unit is managed using the user-friendly GHL Control Center software, which employs a graphical interface (GUI) with drop-down boxes, eliminating the need for complex coding to set up most functions.
• Programmable Logic: While easy to set up, it offers deep, sophisticated programmable logic for controlling complex scenarios and inter-device reactions within the aquarium system.
• Accessory Integration: It seamlessly integrates with GHL's ecosystem of accessories, including the GHL Doser 2 (which features highly accurate 24V stepper motors) and controllable power bars, for complete system automation.
• Robust Build Quality: The device is known for its durable and high-quality build, which contributes to its long-term stability and reliability.
• Data Logging: It is capable of logging data for various parameters, which is particularly useful for tracking trends and for use in scientific studies. 

Benefits:

• Stability and Reliability: The primary benefit is the "rock solid" stability it provides. Users, from hobbyists to researchers, rely on it to run critical life support systems without failure, preventing catastrophic equipment malfunctions or environmental swings.
• Comprehensive Control: It allows for centralized, precise control over the entire aquarium environment (lighting, temperature, pH, pumps, dosing), ensuring all parameters remain within safe ranges.

Kit Components:

• GHL ProfiLux 3.1T ex computer: The main head unit with a LAN port and various sensor inputs.
• Powerbar: A controllable power strip (commonly a Powerbar 5.1 or 6-way) used to switch connected devices (pumps, lights, heaters) on and off, or dim them if a dimmable powerbar version was included.
• Temperature probe: For accurate and continuous monitoring of water temperature.
• pH probe: A standard pH electrode for measuring acidity levels.
• Conductivity probe: For measuring salinity or total dissolved solids (TDS) in marine aquariums.
• Level sensor(s): Typically float switches for automated top-off (ATO) or overflow protection.
• Calibration fluids: Solutions for calibrating the pH and conductivity probes.
• USB cable/adapter: An adapter lead to convert the serial port to USB for PC/laptop programming.
• CD/Software download access: Access to the GHL Control Center software and documentation
