Conductivity in Research & Education

Conductivity in Research & Education

Water chemistry pertaining to conductivity, total dissolved solids (TDS), and salinity, is fundamental in curricula from elementary, to post-secondary education, and applied throughout advanced research institutions. Its application spans multiple disciplines within chemistry, biology, and environmental studies. AlpHa’s conductivity portfolio features contacting (2 cell, 3 cell, and 4 cell), and toroidal (inductive) sensing technologies to provide optimal combination of performance, durability, cost, and ease of use.
