Water Quality Monitor for Maximum Deployment Times

El WQM X es idóneo para el monitoring sin vigilancia y utiliza el control de caudal activo, el bloqueo de caudal pasivo, el bloqueo de luz, la inyección activa de biocidas e inhibidores pasivos para combatir de forma eficaz y segura la suciedad e incrustaciones en el interior y el exterior. Con la minimización de las incrustaciones, la excelente estabilidad de los sensores WQM se traduce directamente en una calidad excelente de los datos a largo plazo.
