A variety of pH electrodes for use in different applications.

• ARGENTHAL™ reference system: AgCl granulate-filled cartridge supplies the silver ions for the chemical reaction on the conducting wire; silver ion trap stops the Ag+ ions from discharging into the electrolyte solution, thus preventing contamination of the junction when using sulfides and proteins
• SteadyForce™: Reference system in which the electrolyte is pressurised (3 bar) to ensure discharge of electrolyte even in viscous samples
• MultiPin™: pH/temperature
