Description
Oakton 27504-00 Combination Ion-Selective Electrode (ISE), Ammonium (NH4+)

- Ion-selective electrode: Ammonium (NH4+)
- Type: PVC membrane
- Concentration range: 5 x 10–6 to 1.0 M (0.1 to 18,000 ppm)
- Temperature/pH range†: 0 to 50°C/4 to 10
- Interferences‡: K+
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.
