A glass bodied reference electrode half cell with a 12mm body. Electrode requires separate pH and ORP electrodes for use. The calomel electrode is an Hg/HgCl system with a ceramic reference junction. The electrode is refillable with saturated KCl. Separate reference electrodes are superior to the reference half cells found in combination electrodes as they have a larger reservoir of filling solution and therefore a faster flow rate of electrolyte which provides faster response and greater stability. Calomel electrodes are Tris resistant and easily cleaned.

• Glass body 12mm diameter
• For use with pH, ORP and ISE’s
• Fast flow rate ceramic frit junction

Supplied with a metre cable and 2mm pin connector.
