Weiss manufactures many kinds of Ion-selective electrodes such as solid state and gas sensors, but it also carries other type of ISEs mainly PVC membrane electrodes from other respectable companies for the convenience of customers.

Really-Flow™ Solid-State combination Ion-selective Electrodes

Weiss Really-Flow combination Ion-selective electrodes have a free flowing junction and provide adjustable optimal flow rate, resulting in more accuracy and repeatability. The junction design permits easy cleaning, which improves performance and extends the electrode’s life. These long-lasting electrodes have no ceramic or fiber junction to clog. Viscous, abrasive and dirty (e.g. slurry) samples are no problems for these electrodes. Just press down on the cap to open the sleeve and flush, renew the junction; release the cap and you are ready to take more measurements. The Really-Flow™ ISEs also have a small volume measurement feature.

 

 

 

Half-cell, solid-State Ion-Selective Electrodes

Half-cell, solid-state ion-selective electrodes are constructed by a highly chemical resistant epoxy body and specially formulated sensor material for lasting and accurate performance. The half-cell electrode's features are easy-to-use and require low maintenance. These solid half-cell ion-selective electrodes must be used with a reference electrode. The ideal reference electrodes are Weiss Carry-over Contamination Free, Sleeve-type, double-junction glass body reference electrodes. Please check the reference electrode section.

 

 

 

Glass body Double Junction Ion-Selective Electrodes

Weiss offers two type of double junction glass body Ion-selective electrodes, refillable and gel sealed, both are designed for routine laboratory and field use. Glass body ion-selective electrodes are most suitable for applications where epoxy body electrodes can not be used due to the sample solution containing organic solvents or corrosive chemicals which can damage epoxy body electrodes.

Gel or ElectroJelly™ sealed glass body Ion selective electrodes can be easily adopted to industrial processing use. For details, please check Industrial processing Ion-selective electrodes page.
