Description The GHL Optical Level Sensor has a PS/2-plug with a 3 m cable. It is for horizontal mounting only. They are versatile and can be used for a wide range of applications. Possible uses of level sensors provided by the ProfiLux Controller: Auto Top Off with one or two sensors Automatic water change Leakage detection 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. Calibration can be carried out by our menu-guided system in the ProfiLux Controller. All sensors are galvanically isolated and can therefore easily be used in parallel in any combination. Warranty and Guarantee for Sensors Sensors are items that wear out during normal use. The life span of a sensor is dependent on the environment and operation conditions. Due to many variables, it is not possible to offer a credible guarantee for a minimum life span. Electrical and mechanical sensors can operate for several years with normal care. Therefore the legal warranty is not valid for these kinds of parts. Nevertheless, we wholeheartedly back the quality of our sensors by offering following guarantees: Electrical sensors and mechanical sensors (level-sensor, temperature-sensor, conductivity-sensor, humidity-sensor) will be replaced in the first 12 months after purchase.)* *Appropriate use, correct maintenance, and care is required. We offer no replacements for broken glass or other mechanical damages.
