The HI4114 is a liquid membrane, combination ion selective electrode (ISE) for the determination of potassium (K+) in solution. The PVC membrane comprised with organic ion exchanger produces a potential change due to the potassium ion exchange between the organic polymer membrane and the sample. The internal sensing elements are housed within a durable polyetherimide (PEI) body.
The HI4114 is ideal for a variety of applications in wine, agriculture, and water analysis.
- Liquid membrane sensor
- Skirted cone geometry
- Detection from 0.039 to 39,100 mg/L K+
