Reagent-free Free Residual Chlorine Meter PRO-20Z Type
Thoroughly pursuing ease of use for residual chlorine management in drinking water and pools.
The PRO-20Z model continuously measures the concentration of free residual chlorine in the water using the polarographic method. When a specific voltage is applied to the electrode sensor immersed in the water, a current flows that is proportional to the residual chlorine concentration. This current is precisely measured and displayed digitally as the residual chlorine concentration value.
