70 DW SERIES
MULTIPARAMETRIC CONTROLLER FOR DRINKING WATER TREATMENT
The 70DW Series is a cutting-edge controller offering simultaneous display of as many of eight measurements for the monitoring and management of primary and drinking water plants.
The 70DW Series’ intuitive interface simplifies measurement calibration and setting of dosing parameters and, in the absence of flow, a dedicated digital input immediately ceases dosing and sends a signal via an alarm relay.
