| ELIT ISE - Solid-State Ion-selective Electrodes |
The ELIT solid-state 8 mm diameter Ion-selective Electrodes are high-quality ISEs which can be combined with a Reference electrode in an easy to handle "Electrode Combination" by means of an Electrode Head.
The advantages of this "Electrode Combination" against other Combination Electrodes are: |
- The Ion-Selective Electrode can be stored dry and the Reference Electrode can be stored wet, which increases the storage and working life considerably.
- The Ion-Selective Electrode and the Reference Electrode can be replaced independently.
- One Reference Electrode can be used with ISEs for various Ions.

Available for the Ions as shown in the Table on the Left.

Reference Electrodes are necessary to complete / close the electrical circuit / loop when Indicator Electrodes like pH-, ORP-and Ion-selective Electrodes have no built-in reference system.
Fig. 1 shows a Gel-filled Reference Electrode with Plastic Body (EAI-R02) and a Refillable Reference Electrode with Glass Body (EAI-R01).
The Electrode with Plastic body is more robust and suitable for field-measurements.
The Electrode with Glass body has a more stable signal output for high precision measurements and long-term measurements.
