Our new redox/orp electrode S-13 is a very sensitiv, snap and exact redox electrode for the measurement in liquids. By its BNC connection it is compatible to almost all redox measuring instruments such as e.g. all devices offered by us. The S13 is the original spare part for our controller P11, P12, P13 and P17.

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.

This type of electrodes does not work with digital controlers made by:
Aqua Medic, Dennerle, Dupla, EME, GHL, HANNA, Hobby, JBL, Sera, Tetra, Tunze. For this types please use our special ph electrode S17. To decide which electrode is the most suitable for your device and appplication please see our electrode guidebook:

For calibration we recommend our calibration liquid (FL3), for maintenance our 3mol maintenance liquid (FL1) and our cleaning liquid (FL5). All available in our shop.
