About Libutec
Libutec GmbH & Co. KG, based in Langenfeld (North Rhine-Westphalia), manufactures electrochemical measuring and sensor technology and distributes it under the designation 'Environmental Engineering Specialty Products'. The product portfolio includes pH and redox single and combination electrodes, reference electrodes, sensors for swimming pool technology (single-rod measuring chains, potentiostatic chlorine electrodes), Memosens electrodes, Pt100 temperature probes as well as immersion and flow-through fittings. In addition, microprocessor-based measuring transmitters and controllers, measuring-control-dosing systems for swimming pools and whirlpools, pH meters and simulators as well as calibration solutions (pH buffers, KCl, redox, conductivity and cleaning solutions) in bottles and Cubitainers are offered. Products are manufactured in glass and plastic versions with glasses for standard to high-temperature/high-alkaline applications, PTFE, ceramic, zirconium and annular gap diaphragms as well as platinum and gold sensorics and Ag/AgCl reference systems. Many electrodes are available as custom-made products or compatible with systems from Alldos, Grundfos, Lutz-Jesco, Dinotec, Descon, Siemens/Wallace & Tiernan, Evo Aqua, Aquacontrol, WTW and Hach Lange. Customer industries include swimming pool technology, water and wastewater treatment, environmental and process engineering as well as measurement and control technology.
