Online redox measurement places higher demands on an electrode than a quick manual check. GR 175 is built for installation in fittings and longer measuring tasks, with a pressure-resistant design for operation up to 6 bar and a PG 13,5 thread for integration.
The long-term stable, low-maintenance reference system supports stable measured values over an extended period. A gel electrolyte, 2 x ceramic diaphragm and platinum dome form the measuring chain for redox measurement across ±2000 mV, at 0 ... 80 °C and > 100 µS / cm.
The glass shaft is useful where plastic shaft materials are not suitable, including media with organic solvents. GR 175 is available with BNC or S7 connection, with the S7 version requiring a suitable connection cable.
The electrode records redox potential in mV and is operated with suitable measuring instruments in mV mode.
GR 175 uses a gel electrolyte (3 mol/l KCl) as part of its integrated redox single-rod measuring chain.
The electrode includes a PG 13,5 thread for installation in suitable fittings and assemblies.
GR 175 is available as GR 175-BNC with BNC connection or GR 175-S7 with S7 connection.
The measuring chain combines a platinum dome with 2 x ceramic diaphragm in a glass shaft.
