Multi-Channel Controller TOPAX DX

Important values securely under control


Supporting Documents:

The TOPAX DX is based on the longstanding experience of many generations of TOPAX controllers from Lutz-Jesco. Its modular design makes it an adaptable and a highly compatible partner in measuring and control technology. With the option of connecting it directly to a variety of sensors to measure the water parameters the TOPAX DX fulfils all the needs for optimal water preparation.
