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.
- 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.
