The 2005031.VIT is a Sodium Ion Electrode Cartridge (NA). The measurement range is 0.2 ppm to 100,000 ppm, the temperature range is -0°C to 80°C. The 2005031.VIT has a glass membrane. The NA electrode is designed for use in aqueous solutions only. The optimum pH range is 6-12 pH. In the acidic solutions the sodium ion electrode, Na+, is interfered by the hydrogen ions, H+, and in alkaline pH solutions, above pH 12, the cations present swamp out all but the highest levels of sodium ions. Lithium ions, potassium ions and ammonium ions all interfere with the sodium measurement. Wetted materials are PES, PTFE, Glass and VITON. Use code "084" to order the 2005031.VIT in an S80 sensor.
