Providing reliable chlorine measurements in Water Treatment Plants since 1959
No.1 Process analyzer supplier to Japanese market*
"Reliable Chlorine monitoring and minimize Chlorine injection"
"Continuous automatic cleaning and achieved less maintenance time"
"Maintenance remotely and reduce maintenance time"
Many of our customers face these challenges - Yokogawa Chlorine Analyzers resolve them.
The RC800D residual chlorine analyzer employs a polarographic system that uses rotating platinum electrodes to provide a continuous online measurement of residual chlorine concentration. It is possible to separate residual chlorine (free chlorine + combined-chlorine) from free chlorine for measurements by appropriate use of reagents.
The RC800D is suitable for various water condition measurements and gives you a stable and high-quality measurement thanks to the rotation electrodes and superior reagent pump.
The RC800D is intended for water distribution measurements at pumping stations, water delivery points, schools, and public facilities.
