Free Available Chlorine Analyzer (Non-reagent Type) FC500G

FC500G non-reagent free available chlorine analyzer adopts the polarographic method, using a rotating electrode to continuously measure online the concentration of free available chlorine.

The FC500G is intended for measurements in the water distribution network, at pumping stations, water delivery points, schools, and public facilities.

Features

  • Measuring range can be selected from 0 to 1/0 to 2/0 to 3mg/l and 0 to 5/0 to 10 mg/l.
  • Rotating electrode/ceramic bead cleaning has been improved to making cleaning automatic and continuous.
  • Easy-to-maintain (-clean) cell construction.
