WTW offers decades of expertise in high quality, rugged conductivity cell technology, and now the new IDS conductivity cells build upon this proven technology including the automatic transfer of the cell constant feature to eliminate operation errors.
Two models are available to cover the entire conductivity range:
The four electrode cell TetraCon® 925 for medium and high level conductivity samples, and the two electrode cell LR 925/01 with flow-through vessel for pure-water and low conductivity samples.
