General description

Short, narrow stem with bulb guard
The combination of a pH indicating and Ag/AgCl reference half-cell in one electrode provides ease of handling and smaller sampling requirements. Combination double junction electrodes are Tris compatible with a maximum temperature of 80°C, and are recommended for proteins, metal ions, sulfides or other substances that will react with either Ag or AgCl. Combination Ag/AgCl electrodes are suggested for higher temperature applications (100°C). Both types supplied with a 30 in. lead.

Temperature Range:
  • -5 to 100°C Continuous Use
  • -5 to 130°C Intermittent Use
