Ion-selective Memosens sensor for the wastewater industry

ISEmax CAS40D is the right technology for trend measurement directly in the basin. It helps you to increase the efficiency and reduce the energy costs of your aeration processes. The sensor works without reagents saving you even further money. With its robust ion-selective membranes and excellent self-cleaning, it eases your maintenance tasks. Thanks to Memosens, CAS40D combines maximum process and data integrity with best operating comfort and simplifies predictive maintenance.
