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 modelsfeature extra-longconnection cables(3 m), which arespeciallymadefor usein the aquarium hobby. Allsensorsare galvanically isolated and canthereforeeasily be usedin parallelin any combination. Please notethebelowexplanations ofwarranty and guaranteeof sensors.
Calibration can be carried out by our menu-guided system in theProfiLuxController.
In the section, “sensor accessories”we also offer varioussensorholders, calibration fluids,cable extensionsandmaintenance kits.
The following sensors are available:
pH, Redox, Conductivity, Oxygen Sensors
Niveau Sensors
Water Temperature, Air Temperature, and Humidity Sensors
Sensors are items that wear out during normal use. A sensor's life span depends on the environment and operation conditions. Due to many circumstances, it is impossible to make an exact prediction about the lifespan. For electrochemical sensors, a life span of 6 to 24 months is common. Electrical and mechanical sensors can operate for up to several years with normal care.
Therefore the legal warranty is not valid for these kinds of parts. Instead, GHL offers the following limited warranty for sensors:
Electrical and mechanical sensors (level sensor, temperature sensor, conductivity sensor, humidity sensor) will be replaced in the first 12 months after purchase.) *
Electrochemical sensors (pH-electrode, redox-electrodes, oxygen-sensor) will be replaced in the first 6 months after purchase.) *
*Valid from the date of the original invoice, a copy of the original invoice is required. Appropriate and intended use, correct maintenance, and care are required. We offer no replacements for broken glass, damaged cables or connectors, or other mechanical damages.
