C1900 ORP and pH ChemLink™ Controller
Section 2. System Overview
2.1
Overview
The ChemLink controller automatically monitors and
maintains both the sanitizer level and the pH balance
in swimming pools, spas, or any circulating water
system that requires water chemistry management.
Designed for easy installation and operation, it can be
used with liquid feed pumps, granular and tablet erosion
feeders, ozone generators, and salt chlorinators. It is not
warranted or recommended for use with chlorine gas
systems.

During the filtration cycle, the controller maintains
sanitizer levels and pH balance by constantly measuring
the Oxidation-Reduction-Potential (ORP) and pH
balance of the water. If the sanitizer level (ORP) or pH
falls below a predetermined set point, the controller will
activate an optional chemical feeder.

Flow Cell Overview
The flow cell assembly houses the sensors and provides
a sample port for manual testing. It also contains an
integrated flow switch/flow indicator that prevents the
feeder(s) from feeding if there is insufficient flow. If
flow is insufficient, a warning message will flash at the
bottom of the screen.
