4. Controller
The EASYPOOL SMART 0 water sampling station is equipped with the TOPAX DZ SMART multi-channel controller. This device uses the
TOPAX DX technology designed for public swimming pools and has been specially configured for use in non-DIN 19643 operated swim-
ming pools. It features a graphic colour display, an intuitive user interface with support for the installation and maintenance of the water
sampling station.
