pH electrodes of the FlowLine series

In media with suspended solids or low conductivity, the liquid electrolyte protects from clogging (including platinum diaphragm) and ensures stable measurement. In case of sulfides present, the risk of electrode poisoning is reduced.## FlowLine pH combination electrodesIn water and media with very low conductivity (50 … 200 µS/cm), as well as in applications with suspended solids or extreme pH values, we recommend using pH electrodes with a liquid KCl reference electrolyte.The electrolyte is continuously supplied to the measuring medium through the junction. This minimizes interference potentials that can cause measurement errors and improves response time by increasing conductivity around the electrode. At the same time, it helps prevent junction blockage and extends the service life of the sensor.Electrodes of this series operate reliably and accurately even in demanding media, whether in the chemical industry, food production, biotechnology, waste incineration, the paper industry, power plants, or plastics processing.- Refillable liquid electrolyte of the reference electrode.- Highest possible measuring accuracy by reducing the junction interference potentials.- **Very quick response behavior.The FlowLine pH combination electrodes feature a glass shaft in different length and a diameter of 12 mm (0.47 in), with liquid electrolyte and integrated plastic adapter for hose connection incl. Pg13.5 thread, platinum junction, sphere membrane, and a measuring range of 0...14 pH. To help you find the right electrode for your application, FlowLine electrodes are available in various installation lengths, with or without an integrated temperature sensor, as well as the following configuration options: * ### Models:#### Electrodes with temperature measurementThe FlowLine combination electrodes with integrated temperature measurement come with a Pt1000 temperature sensor and a VP screw plug head:- FL A 91-120 MF VP pHT pH combination electrode, electrolyte L 200, A glass, length 120 mm, -30...+100 °C- FL H 91-225 MF VP pHT pH combination electrode, electrolyte L 300, H glass, length 225 mm, 0...+135 °CElectrodes including temperature are also available with Memosens connection#### Electrodes without temperature measurementThe FlowLine combination electrodes without integrated temperature measurement come with a coax screw plug head and electrolyte L 300.
