Description

For routine pH and titration measurements with small samples and small vessels, where separate half-cell electrodes may be impractical

 

• 0 to 14pH range
• Porous ceramic junction
• Twist-open/twist-close cap for easy filling
• Constant distance between FS-5 Universal Glass pH bulb and reference junction means high reproducibility
• Immersion depth, ∽4 in. (10.1cm)
• 30 in. long (76.2cm) leads, except 13-620-91, which has 60 in. long (152.4cm) lead

 

Choice of Ag/AgCl Single- or Double-Junction internal reference elements

• Single-junction models with Ag/AgCl reference are perfect for routine pH and titration measurements of aqueous solutions with small samples, small vessels
• Double-junction models with Ag/AgCl reference are useful in aqueous and nonaqueous solutions, and in applications requiring TRIS buffers
• For aqueous and nonaqueous samples
• Double-junction Ag/AgCl eliminate measurement and clogging problems when used in research with Tris buffers
