Wet Chemistry Analyzers

Perform Water Analysis with Accuracy


Keeping water quality at optimal levels for steam generation is essential to preventing inefficiency and premature corrosion or failure of turbines.

Yokogawa's Wet Chemistry Analyzers are highly reliable and used for water analysis of sodium, silica, hydrazine, and phosphate, helping operators minimize and mitigate the increased risk failures caused by corrosion and associated component failures.

Power plants and other steam generation processes use water as their main medium, either for cooling in liquid phase or in gas phase as a drive for turbines. Sodium, silica, hydrazine, and phosphate are commonly measured in makeup and boiler feed water, inside the boiler drones, for boiler blowdown, demineralized water, and in steam condensate water for leak detection.
