EDT directION mini Ion selective electrodes are rugged solid state sensors that can be used in

conjunction with any reference electrode half cell to make a complete Ion sensor.

These mini ISEs are the sensing component of the half cell and Combination ISE's produced by

EDT directION and can be used to build your own ISE to suit your application. They can also be

used as a Micro alternative to 12mm half cell. Micro reference half cells are available on request.

There are two basic sensor constructions: PVC on a solid state substrate and Crystal membrane

with a solid state contact. The Fluoride mini ISE is of Crystalline structure and may be polished and

cleaned as the electrode gets older. Cleaning the membrane with Methanol is usually sufficient.

The lack of internal solution means that lifetime is enhanced and submersionis possible as the

sensor does not flex under reasonable pressure.

The solid state sensors have a huge advantage over conventional ISEs in that there is no internal

fill solution to degenerate the sensor this means that EDT direction mini ISEs have an un-rivalled

lifetime and a very low cost of ownership.

For optimum results use EDT direction standards and Ionic Strength Adjustment Buffers ( ISABs).

The technical specification is the same as the half cell equivalent Cat. No. 1221.
