Nitrate (NO₃⁻) Ion Selective Half-Cell Electrode PNO3-1-01

Overview

The nitrate ion selective electrode PNO3-1-01 is a half-cell (indicator) electrode. It carries a pvc membrane sensing element in an organic glass body. Specifically, it measures NO₃⁻ from 1 × 10⁻⁵ – 0.1 M (620 µg/L – 6.2 g/L) at 5 – 60 °C and a working pH of 4 – 9. However, High concentration anion interfere.

Because it is a half-cell, you use it together with a separate reference electrode. The manufacturer specifies: 232–01. In addition, the BNC(Q9) connector fits benchtop ion meters and titrators with separate indicator and reference inputs. As a result, you can choose the reference system and the outer filling solution to suit your sample.
