WA-200 series Waste Water monitor
Overview
WA-200 series auto drainage water monitoring system is monitoring Turbidity, Conductivity and Dissolved Oxygen in drainage treatment facility. Submersible and Flow through type can be selectable upon field site conditions. According to combination of flat surface sensor and auto cleaning function, it enables long-term operation in addition to maintenance advancement.
Features
- One touch calibration (WA-200 transmitter)
- To be employed Red LED poorly influenced by sample color (Turbidity sensor)
- To be employed flat carbon electrode (Conductivity sensor)
- To be employed cap type membrane sensor ease to replace membrane. (Dissolved oxygen sensor)
