The basic concept of measurement with the AquaSens chlorine measuring cell consists of a 2-electrode cell, a working (Pt) and a counter-electrode (Cu). This continuous potentiostatic measurement does not require a diffusion membrane, which significantly increases the response sensitivity. The special AquaSens flow fitting ensures a constant sample water flow and guarantees easy cleaning of the copper electrode without mechanical devices. The AquaSens chlorine measuring cell also copes well with very heavily polluted water. Together, the measuring cell and flow fitting form a compact measuring device.
