All GHL measurement electrodes are made of the highest laboratory grade. They are durable, low maintenance, and matched to the highest German quality standards.
Only double junction pH and redox/ORP probes are used, never the cheaper and less reliable single junction probes.
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.
We also offer various sensor holders, calibration fluids, cable extensions and maintenance kits. An overview can be found below in the section, “sensor accessories”.
All sensors are galvanically isolated and can therefore easily be used in parallel in any combination.
Please note the below explanations of warranty and guarantee of sensors.
pH, Redox, Conductivity, Oxygen Sensors
Possible uses of level sensors provided by the ProfiLux Controller:
- Auto Top Off with one or two Sensors
- Automatic Water Change
- Leakage detection
Optical sensors and float switches are versatile and can be used for a wide range of applications.
Water Temperature, Air Temperature and Humidity Sensors
Keep track of your pump and filter performance.
With our flow sensors, you can control the flow rate of your pump and filter.
If flow deviations are detected, ProfiLux can set off an alarm and notify you.
- Measures the flow rate of a circulation pump or external filter.
- Connects to the level input of ProfiLux.
- Low maintenance and robust; measurement is made without dirt-sensitive moving parts.
- Incl. PS / 2 M12 cable (2 m) for the connection to ProfiLux.
- Available in 3 ranges.
Please note that the delivery does not include connecting adapters for tubing or tubes.
Leckage-Sensor und Leckage-Interface
Play it safe with the flow early warning system of GHL:
The 80 spring-loaded contacts can detect leaking water.
If a leakage occurs, the ProfiLux computer can warn you via an acoustic signal, SMS, and/or email. If desired, it can also turn on/off specific devices in-advance.
A leak interface is required to connect leakage sensors. Any number of sensors can be connected to the interface.
- Incl. (1.5 m) connection cable to Leakage-Interface
- 2 mounting holes
- A second connector allows you to daisy-chain several leakage sensors to increase safety with additional measuring points
Leak sensors only detect conductive water and are not suitable for use with osmosis water.
Warning: Sensor must not be submerged! Only the 80 contacts on the bottom side should be moisturized.
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. For electro-chemical sensors, a life span of 6 to 24 months is common. 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.) *
Electrochemical sensors (pH-electrode, redox-elektrode, oxygen-sensor) will be replaced in the first 6 months after purchase.) *
*Appropriate use, correct maintenance, and care is required. We offer no replacements for broken glass or other mechanical damages.
