Water Quality Sensors



ISE is a reference electrode immersed in a solution of fixed ion concentration separated by a membrane containing a chemical compound that reacts with the ion of interest, measuring electrical potential that varies with concentration.



Applications for Hydrolab’s Nitrate ISEs include: Tracing the movement of point- or non-point source pollutants (for instance, runoff from agricultural operations) Monitoring aquaculture projects for excessive waste concentrations Surveying nutrient levels in natural water bodies Nitrate – small changes in biologically available nitrogen levels can dramatically affect the levels of microbiological, plant, and eventually, animal life.
