The new Navigator 600 phosphate analyzer from ABB Instrumentation greatly reduces the amount of reagents and maintenance associated with phosphate monitoring while providing high accuracy and reliability. Designed for phosphate-dosed high-pressure boilers in the power generation industry, the Navigator 600 phosphate analyzer provides accurate monitoring of phosphate concentrations (0 to 15 ppm PO4) in a single device. The analyzer is available in single- or multi-stream configurations, enabling up to six streams to be monitored sequentially. It provides current loop, Ethernet, and optional Profibus DP V1 outputs. The phosphate analyzer also uses one-tenth of the reagents consumed by competitive units. A carefully designed wet section reduces maintenance and adds remote management, automatic calibration, zeroing, and cleaning. As a result, the analyzer can operate unattended for three months. (
