Art.No.: DW17/DW17-D
Keywords: Multi-parameter water quality monitoring, Multi-parameter Probe
Supplier: Qingdao Watertools Technology Co.,Ltd.
DW17 Series is centered on CTD (conductivity, temperature, depth) measurement, with two reserved sensor expansion slots allowing up to two additional sensors to be integrated simultaneously. Proven integrated configurations include CTD + turbidity, CTD + pH, CTD + CDOM, CTD + dissolved oxygen, and CTD + chlorophyll + turbidity. The DW17 standard packages include user-friendly software and cables, offering a simplified and efficient solution for research, monitoring and engineering applications.
Features
