Descriptions

The InLab® Expert Pro electrode has been designed with long life in mind.

The fine-pored ceramic junction used in conventional electrodes can easily become contaminated in critical media such as suspensions and wastewater. In contrast the InLab® Expert Pro electrode with a solid polymeric electrolyte requires no junction at all. As a result these sensors are particularly insensitive to contamination.

The reference electrode on these sensors is in direct contact with the measured medium by means of two open junctions, hence there is no junction to block. In addition, the high grade plastic (PEEK) shaft offers a high level of chemical resistance and robustness. Service life and measurement accuracy are further improved by the ARGENTHAL™ reference system which reduces loss of silver chloride from the reference wire at differing sample temperatures.
