HI-4113-53 Nitrate Module for Combination
HI-4113-53
Nitrate replacement modules, 3 pack for Combination Ion Selective Electrode.
- Nitrate-sensitive polymer
- Durable PVC matrix
- Easy to replace
The HI-4113-53 contains three replacement sensing modules for the Nitrate Combination Ion Selective Electrode. Easy to fit.
The HI-4113-53 nitrate module is for use with the HI-4113 nitrate combination ion selective electrode (ISE). The liquid membrane sensor contains an organic polymer within the inert PVC matrix that is responsible for exchange of nitrate ions across the membrane. A charge imbalance develops between the sample and the internal cell in response to the nitrate ion activity. The potential change is proportional to the concentration of ions in solution.
The HI-4113-53 nitrate combination module easily screws onto the HI-4113 probe body, allowing for quick assemblage or replacement. Pre-soaking the nitrate sensor in a dilute standard without ionic strength adjuster (ISA) for at least one half hour before calibration will help to optimise the sensor response. Refrigeration of the HI-4113-53 nitrate module will help extend its life.
