This file introduces the HI 4013 and HI 4113 half-cell and combination electrodes, used to measure nitrate ions in aqueous solutions.
This manual provides instructions for the Hanna Instruments HI 4013 Nitrate Half-cell and HI 4113 Nitrate Combination Electrode. These ion selective electrodes are designed for the measurement of nitrate ions in aqueous solutions, utilizing a replaceable sensing module with an organic polymer membrane. The HI 4013 requires a separate reference electrode, while the HI 4113 is a combination electrode with an internal Ag/AgCl reference.
| Concentration range | 6200 to 0.62 ppm |
|---|---|
| Operating Temperature | 0-40°C |
| Operating pH | 3 to 8 pH |
| Dimensions | 12 mm (OD) X 120 mm |
The electrodes operate between 0-40°C and a pH range of 3 to 8.
Yes, the HI 4013 is a half-cell electrode that requires a separate reference electrode to complete its electrolytic circuit.
For long term storage, the sensing module should be unscrewed from the handle and stored dry in the shipping vial.
