Silver-Silver Chloride with ceramic junction. Double junction with one refillable chamber. Glass body 12 mm O.D. x 150 mm long. Recommended for use with most specific ion electrodes. Temperature range: 0 to 100°C continuous use, 100 to 130°C intermittent use(glass body electrodes). The Ag/AgCl reference is also a very stable half-cell that has a much higher working temperature than the calomel reference. Recommended for all applications except those involving Tris buffer, proteins, metal ions, sulfides, or other substances that will react with either Ag or AgCl. Pin connector.
