Self-powered water quality system all around the city.
Water Quality Monitoring for Smart Distribution Networks
High-precision water quality measuring and analysis, online data collection and streaming make the WQA-600 Series an integral component of ‘intelligent’ operations in water distribution systems. The device facilitates monitoring for a reliable, efficient and safe smart water distribution network, at every critical point along the network.
6-Volt Multi-Parameter System
The best solution for gathering and communicating water quality data without relying on external power supply. The built-in low energy and long-life battery pack is enhanced with automated and on-demand measurement settings. Measurement frequency can be switched to turbo mode when a water quality event is detected.
VERY Easy Installation & Maintenance
Long-term battery operation along with minimum calibration requirements and waterproof casing allow for reduced site visits and minimized maintenance. Ideal for isolated locations and network points without power supply.
