Range: 0 – 5ppm

Range: 0 – 150ppm

Range: 0 – 300ppm

The Waltron 3041 Silica Analyzer is the first choice for online analysis of dissolved silica in ultrapure water applications. The 3041 is trusted worldwide to deliver reliable readings with minimal maintenance and low total cost of ownership. An enhanced color touchscreen user interface makes the 3041 easy to operate and configure, and the clever fast-loop reservoir feature allows accurate measurement, independent of flow. Common application points in a boiler system for online silica measurement include: make-up water, condensate, boiler feedwater, saturated steam/main steam, and cooling water.
