All GHL measurement electrodes are made of the highest laboratory grade. They are durable, low maintenance, and matched to the highest German quality standards. Most models feature extra-long connection cables (3 m), which are specially made for use in the aquarium hobby. All sensors are galvanically isolated and can therefore easily be used in parallel in any combination.
