The HI4113 is a liquid membrane, combination ion selective electrode (ISE) for the determination of nitrate (NO3–) in solution. The PVC membrane comprised with organic ion exchanger produces a potential change due to the nitrate ion exchange between the organic polymer membrane and the sample. The internal sensing elements are housed within a durable polyetherimide (PEI) body.
The HI4113 is ideal for a variety of applications in the food industry, agriculture, and water analysis.
- Liquid membrane sensor
- Skirted cone geometry
- Detection from 0.62 to 6,200 mg/L NO3–
