Water sampling station EASYPRO CS


Reliable and individual

With the EASYPRO CS, Lutz-Jesco offers a flexibly configurable system, which is based on the classic open amperometric disinfection measurement with the CS120.

The configuration flexibility means that a customised, very robust solution can be put together for your swimming pool or industrial application, which in the end saves costs because only the most necessary components are installed. .

The design of the base plate allows the CS120 to be used in combination with up to 3 other measurands in the water.

The TOPAX® MC multi-channel controller installed* in the EASYPRO CS subjects the water parameters to constant measurement, keeping them within the target range. It enables you to control a large number of actuators and permits easy and intuitive operation.  

    EASYPRO CS components (fitted on the baseplate)
  • TOPAX® MC multi-channel controller
  • Measuring cells and measuring cell fittings
  • Sample water filter
  • Flow control
  • Flow controller DFR 45 with sampling water extraction point and installed temperature sensor
  • Inflow and outflow tap
  • Bracket for buffer solutions and buffer solutions for adjusting the measuring cells
  • Multi-coloured LEDs
  • The measuring cells are partially packaged separately and not pre-installed.
