Oakton 27504-12 Combination Ion-Selective Electrode (ISE), Cyanide (CN)

• Ion-selective electrode: Cyanide (CN–)
• Type: solid-state
• Concentration range: 5 x 10–6  to 10–2 M (0.1 to 260 ppm)
• Temperature/pH range†: 0 to 80°C/11 to 13
• Interferences‡: S–2, I–, Br–, Cl–

Electrodes are double-junction combination ion-selective electrodes and are convenient to use in places where two electrodes won’t fit. Use with a meter that has a resolution of 0.1 mV for the most accurate results; a meter with direct readings in ppm is preferred.

Economy Epoxy Electrodes have a durable epoxy body and are well-suited for portable field applications. The outer reference chamber is silver-free and resists contamination. These electrodes are refillable.
