Greisinger Redox Electrode GE 105 (102160)

For laboratories, water treatment facilities, and aquarium enthusiasts who need reliable oxidation-reduction potential measurements, the Greisinger GE 105 redox electrode offers a maintenance-free solution. It features a platinum plate sensor and Ag/AgCl reference system with a gel electrolyte, ensuring stable readings without the need for refilling. The ceramic diaphragm provides a consistent junction, while the glass shaft withstands temperatures up to 80 °C. With a BNC connector and 1 m fixed cable, it integrates easily with most ORP meters. The electrode measures from -2000 to +2000 mV and responds in under 10 seconds, making it suitable for water, wastewater, pools, and aquariums.
