Hanna Instruments-4103 Cadmium Combination ISE Electrode
The Hanna Instruments-4103 Cadmium Ion Selective Electrode is a complete potentiometric cell that contains a silver/silver chloride (Ag/AgCl) reference housed within a PEI plastic body with a potassium nitrate electrolyte. The internal elements are isolated from the sample by a compressed Cadmium Sulphide/Silver Sulphide sensing membrane.
Hanna’s solid state combination ISEs are designed with a cone style junction.
Before testing, it is important that the ionic strength of the standards and sample be adjusted to a high and constant value with the ionic strength adjuster (ISA) solution (Hanna Instruments-4000-00).
The Hanna Instruments-4103 cadmium solid state ISE can measure from 0.1µM (0.01 mg/L) to 0.1M (11,200 mg/L).
Key features
Fixed Sensing Modules - Combination solid state ISEs are electrodes that detect free ions in a solution. The highly insoluble, compressed sensing pellet is attached to the electrode by a fixed sensing module for ease of use.
Durable PEI Body - The probe body is composed of durable polyetherimide (PEI) plastic.
BNC Connection - The Hanna Instruments-4103 has a universal BNC connector for easy connection to any benchtop meter with a female BNC probe input.
