For shallow water applications industrial sensors are best choice. Redox ORP combined electrodes are industrial sensors using a solid reference system (stiff polymer mass containing KCl) and an aperture diaphragm which allows direct contact between reference electrolyte and sample medium. The sensors have a standard S7/S8 head and are screwed into a flange with a fitting socket. A coaxial contact makes the electrical connection in the flange. Sealing between sensor and flange is achieved by an O-ring, which is part of the sensor.
The redox sensor is supplied with a storage solution in a wetting cap. The cap must always be placed beneath the sensor and contain sufficient storage solution to store the sensor when not in use. The storage solution should be a 3 M KCl solution that prevents the reference electrode from drying out.
The sensor needs replacement after a lifespan of approximately 12 months (depending on the measuring environment).
