Secure your Aquarium with the Optical level sensor GHL V2 (Ref pl-1890). This high-tech sensor, with a 3 meter cable, is designed to provide immediate reactivity and increased strength to soiling compared to conventional floats.
The Optical level sensor V2 is the essential accessory for any owner of ProfiLux controller wishing to automate critical tasks. Its light beam measuring technology provides a millimeter precision, essential to maintain stable salinity in a reef bin.
Thanks to the power of the controller GHL, this sensor allows you to configure multiple management modes:
Unlike the mechanical float sensors, optical sensors do not have moving parts that can lock. Although they are more robust facing dirt, they offer superior peace of mind in environments where limestone or salt accumulates quickly.

💡 The Expert RecifeArt Council: Although very resistant, we recommend cleaning the tip of the sensor with a soft cloth during your maintenance to avoid any biofilm deposit that could eventually alter optical playback. For use in a bucket ofskimmer, prefer a float mechanical sensor, less sensitive to permanent projections.
Used with a ProfiLux controller, this sensor allows you to manage the Auto Top Off with one or two sensors, automate the water changes or serve as a leak detection system.
The optical level sensor V2 offers great flexibility since it can be installed as well horizontally and vertically. It is equipped with a cable of 3 meters and a mini-DIN plug for easy connection.
Unlike contactless sensors that attach to the outside of the glass, the optical sensor V2 is designed to be immersed or placed inside. It is less sensitive to dirt that float models and remains more reliable in environments where the glass wall is constantly wet.
Yes, optical sensors are generally considered more robust because they do not have mechanical moving parts. They are less sensitive to salt accumulation or sediment that could block a conventional float.
