ABB's Navigator 600 Silica analyzer substantially cuts the costs and maintenance associated with silica monitoring in power generation and other large-scale steam and water dependent applications. Many years of experience and innovation in the design and successful application of continuous chemical analyzers has been combined with the latest electronics and production technologies to produce the Navigator 600 Series of analyzers from ABB. Based on colorimetric techniques, they feature a liquid handling section carefully designed to reduce routine maintenance. Utilizing powerful electronics, advanced features such as automatic calibration, continuous sample analysis and programmable multi-stream switching ensure accurate measurement of silica. Analysis of up to 6 sample streams Up to 90% lower reagent consumption than other silica analyzers Labour-saving 5 minute annual maintenance and up to 3 months unattended operation Automatic cleaning and calibration True auto-zero compensates for sample color, turbidity and background silica in reagents Intuitive software with full colour graphical display Data logging and graphical process trending Full audit trail capability Secure data archiving to SD Card Measurement range 0 to 5000 ppb SiO2 (minimum range 0 to 50 ppb) Chemical method Molybdenum blue Sample stream options Available as single-stream or multi-stream (2, 4 or 6 stream) configurations Measurement frequency Continuous chemistry and measurement (programmable sample rate for multi-stream) Accuracy / maximum measured error ±2 % of reading or ±0.5 ppb (whichever is the greater) over the range 0 to 500 ppb ±5 % of reading over the range 500 to 5000 ppb
