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 for efficient process management"
Many of our customers face these challenges - Yokogawa Chlorine Analyzers resolve them.
The FC800D non-reagent free available chlorine analyzer adopts the polarographic method, and a unique rotating electrode provides a continuous online measurement of free available chlorine concentration.
The FC800D is part of the SENCOM4.0 platform family and can connect to the FLXA402T. Thanks to a smart unit equipped behind the electrode unit, FC800D gives you more insight into the ordinary operation.
The FC800D is suitable for water distribution measurements at pumping stations, water delivery points, schools, and public facilities.
*Based on a Yokogawa survey in 2019
