The Model FCL is a complete system that measures free chlorine in fresh water.
It includes a transmitter (choice of Model 56 or Model 1056), a 499ACL-01 free chlorine sensor, a pH sensor (if required), and a constant head flow controller. The transmitter and flow controller are mounted on a back plate, and quick disconnect Variopol sensor cables are pre-wired to the transmitter, making installation and startup fast and easy.
