Measuring and control system DULCOMARIN® 3


New features and functions – a major step for the DULCOMARIN®. A gigantic step for your pool system.
The measuring and control system DULCOMARIN® 3 is a reliable system for the treatment of swimming pool water.
The intuitive menu guidance is also supported by videos and shows step-by-step calibration of the sensors.
It is operated using the system’s touch display. You can also operate the DULCOMARIN® 3 remotely via the Internet. So you can connect to your DULCOMARIN® 3 using your smartphone or any other Internet-compatible end device.

The DULCOMARIN® 3 is the central element of the measuring and control system. All the information relating to the individual pools and associated control circuits is collated here. Every other pool is linked to a DULCOMARIN® 3 module, independently of the distance of the pools. You can calibrate the sensors on site here and also set the parameters.
