For shallow water applications industrial sensors are best choice. The pH electrode incorporates a double pin-hole diaphragm and a gel polymer solid electrolyte, which is AgCl free and thus resistant to sulfides. The electrode allows reliable measurements in e.g. suspensions or sulfide-bearing water. The sensor has a standard S7/S8 head and is screwed into a flange with a fitting socket. A coaxial contact makes the electrical connection to the flange.
The pH 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).
