Monitoring Boiler Feed Water Quality

On-line measurements have become increasingly important in managing the quality of boiler feed water.

Thermo Scientific’s range of analysers is designed to meet your critical measurement needs for contaminants such as sodium, silica and calcium hardness. Orion’s advanced electrode technology and robust electronics are suitable for accurate measurements of De-Ionised water containing extremely low levels of contaminants.

Without accurate and real-time monitoring of chloride, the risk of corrosion fatigue, stress corrosion cracking and pitting can create significant costs in maintenance and downtime. The Thermo Scientific Orion 2117LL chloride analyser is ideal for measuring and monitoring the critical chloride levels in feed water, boiler water or economizer inlet.

Early detection of chloride ingress from feed water helps your plant maintain the optimal balance of water purification with ease and peace of mind.
