WE430 Hydrazine analyzer ensures high precision and real-time hydrazine measurement for optimum efficiency throughout. With the Yokogawa WE 430 analyzer, control and protection of the system is provided with well-balanced performance, ease of use and in same time optimized system.

Features: • Designed for versatility and accuracy• Consistent, precision-maintaining high

performance• Repeatable and verifiable • Easy to operate and calibrate • User selectable calibration modes • Hydrazine detection limits 0 ppb to 200 ppb• Extended reagent consumption

WE440 Phosphate analyzer is optimized for applications that require early detection without compromising the precision of the phosphate measurement. Initial detection results in the reduction of scaling formation, microorganisms, and other effects that decrease equipment efficiency. With the added benefit of reduced reagent consumption, the WE440 leads to an overall lower cost of ownership.

Features: • Optimized reagent consumption reducing OPEX• Accurate and precise measurements for fine

control of Phosphate dosing• Compact size • Simplified operation with intuitive menu

navigation• Low operating costs with low power

consumption and minimal maintenance• On-demand mode for non-continuous operation

– Housekeeping mode for rapid start up
