The spare electrode S-12 is a very sensitiv, snap and exact pH electrode for the measurement in liquids. Due to its small size you can easily use it where there is little place e.g. below a aquarium cover. By its Mini-BNC connection and 1m cable it is compatible to almost all pH measuring using Mini BNC such as e.g. our P05.
In our shop you will also find any kind of PH, ORP, EC, Oxygen, TDS electrodes with BNC and Mini-BNC for liquids as well as for direct soil-, food-, meat- and cheese- measurement or materials of similar consistency.
