These combination electrodes, employing the use of solid gel, were designed with the water industry in mind. Capable of being used with portable instruments, and on-line, they will give optimum performance in cold water. The gel retains salts, and maintains zero potential for a much longer period of time. The mechanical strength of the gel allows the use of a junction with a much higher porosity than previous designs.

This gives the following advantages -

• Fast response time to equilibrium
• Improved accuracy
• Longer electrode life
• Less frequent calibrations
• Greater stability
• Optimum performance in cold water
• Temperature range 0-60°C
• Dims, l x w, mm 120 x 12
• Reference: AgCl
