In comparison to ProfiLux 4, ProfiLux 4e has in the basic configuration one switchable pH/ORP input instead of two and no conductivity input, and in addition the less required S ports (digital outputs / connection for classicpowerbars) have been removed. Otherwise ProfiLux 4e is identical to ProfiLux 4.

An upgrade to the full functionality of ProfiLux 4 is possible at any time later, either by inserting expansion cards or connecting an expansion box.

The ProfiLux® aquarium controller offers everything the ambitious aquarist needs to achieve success.

From form to function, the ProfiLux 4/4e is well-equipped to manage important tasks such as lighting control, water parameter measurement/control, level control, flow measurement, pump control, and much more. Fitted with the most on-board connections available, the ProfiLux 4/4e also includes integrated modules for measuring Conductance (adjustable: fresh or saltwater), Temperature, pH, and Redox. Connections for level sensors, flow sensores, leakage sensors, and 1-10V interfaces are also included.

Built-in WiFi and USB connections ensure optimal connectivity to keep you well informed about the status of your aquarium via web interface, app, e-mail, and myGHL cloud service.

The ProfiLux® aquarium controller is globally recognized for its outstanding accuracy and reliability. From private users to research institutions, they all trust in the ProfiLux to provide them with highly accurate data and performance. The exceptional functionality of ProfiLux makes it the preferred controller of professionals and hobbyists alike.

ProfiLux 4/4e is designed to standout from the crowd. Offering switchable pH/redox and Conductivity (4e: optional) inputs, laboratory grade measurement and accuracy, nearly limitless expansion options, rock-solid hardware, and much more. See for yourself, what it is like to own the ultimate in functionality.

Profilux®4e Connections
Numerous connection options even in the basic configuration, easily expandable at any time
Plug & Play: No additional costly modules necessary to connect the accessories listed in the below illustration, such as sensors (e.g. pH, temperature, flow, leakage, level), 1-10V devices and others

Multi-channel Lighting Control
Control up to 32 independent channels of dimmable and non-dimmable lamps
Freely programmable
True calendar moon phase: Simulates the lunar rhythm in harmony with nature and promotes species-typical behavior.
Sunrise and sunset simulation
Seasonal lighting: ProfiLux Aquarium Controllers (beginning with version 3) are capable of simulating the seasonal cycle of sunshine duration and sun intensity >Learn More
Acclimatisation program for gentle adaption
Thunderstorm simulation: Simulate lighting-effects in conjunction with dimmable GHL lights. Programmable storm parameters allow you to change the frequency, intensity, and duration of a thunderstorm.
Rainy day simulation
Cloud simulation: Programmable random generators allow you to define the beginning, intensity, duration, and speed of a cloud – so each time new clouds are created.
Temperature-dependent light reduction: for short-term temperature peaks on hot summer days.
Tropical twilight
Gentle lighting transition from summer-time to winter-time laid out across several days.
Output via 1-10V interfaces, PWM interfaces or Mitras Lightbar® interface, etc.

Lab Grade Measurement and Controllability
Water temperature monitoring/control: Program heaters, ground heaters, and cooling devices for maintaining temperature; Nightly cooling can also be programmed. Intelligent summer-circuit for optional ground heating.
pH monitoring/control: Program up and down pH regulation via CO2-addition (pH-decrease) or via Alkalisation (pH-increase); Nightly decrease can also be programmed.
ORP/Redox monitoring/control
Conductivity (Salinity) monitoring/control
Oxygen monitoring/control
Humidity monitoring/control
Air temperature monitoring/control
Measurement of KH or Alkalinity
Support of further measurement parameters in preparation
Universally switchable inputs: For pH and ORP/Redox
